When Your Solo Trip's Water Use Exceeds the Local Annual Supply

You're three days into a solo trip in a small coastal town. The shower feels incredible after a long hike. You let the water run while you soap up—maybe ten minutes. Later, you learn that the town's main reservoir is critically low, and locals queue for hours to fill a single bucket. That ten-minute shower? It used more water than the average household here gets in a week. Welcome to the uncomfortable math of solo travel water use.

This isn't about guilt. It's about awareness. When you travel alone, your individual choices—what you eat, where you sleep, how you clean—have an outsized impact. One person's 'small' daily habits can strain a community's water supply faster than a tour group. But here's the thing: you can fix it without sacrificing the trip. This field guide maps the territory: where water goes, what actually helps, and what's just performative eco-anxiety. No judgment, just data and stories from the road.

The Field Context: Where Your Water Footprint Hits the Ground

A solo traveler's daily water tally: beyond the shower

You wake up in your Bali guesthouse, rinse your face, brush your teeth, and flush. That's maybe twelve liters before coffee. But here's the thing—the real footprint starts when you're not looking. A single hotel sheet wash cycle devours 50–70 liters of water, and most mid-range places swap linens daily whether you slept in them or not. Your small load of laundry? That's 40 liters, minimum. The pool you dipped into after the rice terrace hike? Refilling it every three days because of evaporation eats more than a family of four uses in a week. I've watched solo travelers pat themselves on the back for taking three-minute showers while their accommodation's irrigation system hoses down a decorative lawn at noon. That hurts.

Most people underestimate by a factor of five. You count the shower and the drinking bottle. You forget the water embedded in your breakfast papaya, the 1,500 liters that grew the cotton in your t-shirt, the 10 liters per kilowatt-hour behind your air conditioning. The catch is brutal: your solo trip's water use doesn't stay in your room. It leaks into the local supply chain, and in a place already scraping the bottom of the aquifer, that leak becomes a gash.

Real-world examples: Cape Town, Bali, Rajasthan

Cape Town nearly hit Day Zero in 2018. Solo travelers who visited during the drought were asked to use 50 liters per day—total. Most failed. A guesthouse owner I met there told me she watched a German tourist run a full bathtub on day one, then complain the pressure was low. That single bath used her family's two-day allowance. In Bali, the tourism corridor from Canggu to Ubud is pumping groundwater so fast that the island's limestone aquifers are collapsing under saltwater intrusion. Your villa's infinity pool? It's literally pulling seawater into the wells of the village next door. Rajasthan is quieter but meaner. During the 2022 heatwave, solo trekkers in Jaisalmer would buy bottled water by the crate—2,000 plastic bottles per trek—while local women walked three hours to a hand pump. The disconnect isn't malice; it's invisibility. You don't see the empty well because you're in the air-conditioned lobby booking your next transfer.

'A solo traveler using 200 liters a day in a region that averages 40 liters per person per day isn't traveling lightly. They're importing a lifestyle the local ecology can't support.'

— line from a water NGO worker I interviewed in Ubud, 2023

The hidden water in your food, laundry, and accommodation

Here's the math nobody advertises. A single avocado on your toast cost 270 liters of water to grow. Chicken satay for dinner? 4,000 liters per kilo of meat. Your hostel's breakfast buffet with imported cereal, almond milk, and bacon? That plate is a submerged reservoir. The worst offender is almost never the shower—it's the food supply chain trucking virtual water from watersheds you've never heard of. A solo traveler eating three meals out daily, with a mandatory bottle of wine and a steak once a week, can easily push their daily water footprint past 3,000 liters. That's more than a subsistence farmer in the same valley uses in a month.

Laundry is the silent gut-punch. You're in a humid climate, everything feels damp, so you hand-wash a pair of shorts and a shirt. Good instinct. But if you're washing in the sink with the tap running the whole time, you're blowing through 20 liters per item. One I met used her accommodation's washing machine for a single t-shirt and two pairs of socks. The machine's full cycle: 120 liters. She'd have been better off wearing the socks twice. What usually breaks first is convenience—the hotel provides free laundry, so why not? That's where the gap between intention and impact widens into a chasm. You meant to save water. The system was designed to make you forget.

Foundations Readers Confuse: Myths About 'One Person' Impact

The fallacy of small actions: why 'just one person' is a dangerous math

The most common deflection I hear—from travelers, from friends, even from myself on low-moral mornings—is this: I'm one person. Agriculture uses 70% of global freshwater. Why bother? It sounds logical. It's not. That comparison conflates scale with relevance. A single solo traveler doesn't compete with a wheat field, sure—but you also don't live inside a wheat field. You land in a small coastal town where the hotel's well taps the same aquifer the local school uses. Suddenly your 15-minute shower isn't abstract. It's a neighbor's cooking water. The fallacy isn't that you're wrong about percentages; it's that you're measuring impact in the wrong unit. Percentages obscure timing and concentration—when you draw water and where. A farmer irrigates steadily across seasons. A solo traveler hits the same supply in a burst: check-in, shower, laundry, pool, rinse-repeat. That spike can exceed a household's weekly use in 48 hours. The catch? You never see the strain. The hotel hides it behind chlorinated taps and green lawns that shouldn't exist there.

How tourism water use compares to local domestic use — the real ratio

Here's the uncomfortable part: in many destinations, a single tourist uses 3 to 10 times more water per day than a local resident. That gap isn't a statistic I'm inventing; it's baked into the infrastructure of tourism. Resorts demand pools, lush gardens, daily linen changes, and air conditioning systems that dump heat and evaporate thousands of liters. The solo traveler in a guesthouse with a shared bathroom? You're still part of that system—the hotel's supply chain includes laundries, food prep, and cleaning crews whose water budgets assume your room will be serviced daily. The myth that 'individual choices don't matter' collapses when you realize tourism water use often exceeds domestic consumption in water-stressed regions. Not in aggregate—per capita. That means your presence, alone, can double the local demand on a fragile system. Most people skip this thought because it feels like blame. It's not. It's a map.

'I always thought my impact was a drop in the ocean. Turns out the ocean was a puddle, and I was carrying a bucket.'

— overheard at a hostel in San Pedro de Atacama, where the annual rainfall is less than 15mm

The difference between direct and virtual water — what you don't see

Your direct water use—shower, toilet, drinking—is visible, trackable, and honestly pretty small. Maybe 20–40 liters a day on a good trip. The invisible part is virtual water: the water embedded in everything you consume. That avocado toast you ordered for brunch? Roughly 200 liters per avocado. The cotton T-shirt you bought as a souvenir? 2,700 liters. A single 200-gram steak? 3,000 liters. Suddenly your 'negligible' footprint balloons past the local annual supply of an entire household. The painful irony: solo travelers often pride themselves on being lighter than group tours, yet blind spots in food and clothing choices erase that advantage. I have caught myself ordering imported almonds in a drought zone, thinking I was being virtuous by using a refillable bottle. Wrong order. The bottle is a start. The almonds are the leak.

What usually breaks first is awareness—not the water supply. You don't feel guilty about what you can't see. That's the trap. The fix isn't perfection; it's pattern recognition. Check what's in season. Skip the laundry service. Eat street food cooked with local ingredients, not imported bottled water wrapped in plastic. The next section will give you the actual low-water habits that survive heat, fatigue, and the temptation of a cold pool—habits that don't require you to become a monk, just a slightly more awake version of yourself.

Patterns That Usually Work: Low-Water Solo Travel Habits

Choosing accommodations with water-saving systems

Look for guesthouses that have installed low-flow showerheads or dual-flush toilets — not the glossy eco-resorts that slap a "save the planet" sticker on a towel rack. I once stayed at a family-run pensión in southern Spain where the owner had rigged a greywater pipe from the sink to the toilet tank. Crude? Yes. Effective? Absolutely. That place used roughly a third of the water per guest compared to the chain hotel next door. The trade-off is real: these places often lack the polished aesthetic you'd see on Instagram. But you're not there for the bathroom vanity — you're there to move through a place without draining it. Ask directly before booking: "Do you have water-saving fixtures?" If they pause or pivot to their towel-reuse program, that's a red flag. Towel reuse saves detergent, not water.

Timing your activities to reduce laundry and cleaning

Here's a pattern that sounds small but compounds fast: align your sweat-heavy activities (long hikes, cycling, humid city walks) with the day you plan to wash clothes anyway. Most solo travelers I meet do the opposite — they hike first, then wear the same damp shirt for two more days, then do a full laundry load. That's two washes instead of one. The fix? Bundle your dirty activities before laundry day, then wash everything at once. Same for accommodation — if you're staying three nights, skip the daily towel change. Hang it to dry. The catch is social pressure: hostel staff sometimes swap your towel without asking. A simple "no service, please" sign on the door works better than a note. I've had housekeeping ignore the note twice — but that's still a 70% success rate. Not bad for zero effort.

Eating local, low-irrigation foods

Food's water footprint is invisible until you look. A single avocado requires about 70 gallons of water to grow. A plate of lentils? Roughly 18. In arid destinations — think Morocco, Peru, parts of India — eating the local staple diet (rice, beans, millet, root vegetables) slashes your embedded water use more than any shower timer could. The pattern: buy from street vendors who cook what grows nearby. Not the tourist-menu pad thai flown from elsewhere. Not the imported almond milk smoothie. Local, seasonal, low on the food chain. That means more chickpea stew, less beef. More flatbread, less salad greens from a hydroponic greenhouse. One traveler I met in Rajasthan survived ten days on dal bati and chai — and his water footprint was roughly a quarter of mine during the same week. His meals cost less, too. The trade-off? Repetition. You'll eat similar things most days. But monotony beats hypocrisy when you're passing through a drought-stressed village.

'The solo traveler who blames their impact on 'just one person' hasn't yet counted the water in their coffee, their sheets, their laundry — all invisible, all real.'

— overheard at a guesthouse terrace in Seville, after a long discussion about responsible travel

What usually breaks first is the convenience trap — you're tired, it's hot, you grab a bottled water and a pre-wrapped sandwich. That's fine once. But three days in a row? You've doubled your plastic and water footprint compared to refilling a bottle and eating from a market. The patterns above work because they require zero gear, no app, no certification. Just attention. Try one for your next three destinations. See which sticks. Then double down.

Anti-Patterns and Why Teams Revert: Eco-Fatigue and Convenience Traps

The 'I'll offset later' mentality

It's seductive, this one. You're at a remote desert guesthouse, the shower pressure is dreamy, and the local water table is screaming. But you think: I'll donate to a water charity next week. I'll plant a tree. I'll offset. That sounds fine until the next trip — and the one after. The catch? Offsets in solo travel rarely materialize. I have seen travelers stash carbon credits in bookmarks, planning to "sort it out at home." They never do. The mental ledger stays empty.

The real problem isn't bad intent — it's the gap between intention and a concrete action. You finish the trip, laundry piles up, work floods back, and that offset promise evaporates. Wrong order: the offset should happen before you turn the tap. Or better, you just skip the long shower. One concrete fix: pre-pay a local water-restoration project as you book your accommodation. Not later. Now. That closes the loophole your brain loves to exploit.

Using hotel towels multiple days, but ordering bottled water

Most eco-conscious solo travelers proudly hang the towel, signaling "don't wash this." Good reflex. But then they buy three single-use plastic bottles from the minibar because the tap water "tastes weird." That hurts. The towel reuse saves maybe ten gallons over a week. The bottled water habit — shipped, chilled, often from a source that dried up a local spring — undoes that tenfold. We fixed this by carrying a SteriPen and a wide-mouth metal bottle. Took two minutes to explain to skeptical hostel staff. After that? No plastic, no guilt, and the towel stays dry.

What usually breaks first is convenience. You're exhausted after a 14-hour bus ride; the shop is closed; the vending machine glows. You buy the bottle. That's not a moral failure — it's a system failure. The anti-pattern is thinking your towel heroics cancel the bottle purchase. They don't. Trade-off: if you can't solve the water taste issue, you'll revert every time. Pack your own solution before you pack your socks.

"I spent a year patting myself on the back for reusing linens while flying through 40 plastic bottles. The math didn't add up — and I knew it."

— anonymous traveler, overheard in a Kyrgyzstan guesthouse kitchen

Eco-friendly gear that actually wastes water in production

Here's the one that stings. You buy a "sustainable" merino wool shirt — marketed as low-impact, biodegradable, perfect for solo journeys. Noble. But merino sheep need water. A lot of it. A single wool shirt can require over 500 liters of water in the supply chain — grazing, washing, processing. Meanwhile, a cheap polyester shirt uses far less water to produce (though it sheds microplastics). The anti-pattern: we swap one footprint for another, patting ourselves on the back without checking the full picture.

Most teams skip this: production water vs. use water. Your daily shower uses 40-60 liters. That merino shirt you bought for the trip? It consumed ten days' worth of your own shower water before you even wore it. That doesn't mean abandon wool — it means buy less, buy used, or choose hemp or Tencel if you must. I've stopped buying "eco" anything for a trip unless my current gear genuinely failed. The greenest garment is the one already in your bag.

One more trap: "biodegradable" toiletries that require industrial composting facilities — which don't exist where you're traveling. You dump "eco" soap into a mountain stream, thinking it's fine. It isn't. The algae bloom downstream disagrees. That's not eco-fatigue; it's misinformation. Fix: test your products in cold water on a patch of grass first. If suds linger after thirty seconds, don't take them into the backcountry. Simple. Saves the watershed. Saves your conscience.

Maintenance, Drift, or Long-Term Costs: Keeping the Habit Alive

How to sustain water-conscious habits trip after trip

The first trip is easy. You're fired up, reading labels, timing showers like a military drill. By trip three, that edge dulls. I have watched perfectly good intentions evaporate somewhere between a twelve-hour layover and a hostel with no recycling bins. The maintenance phase isn't about grand gestures — it's about building defaults that survive travel fatigue. What usually breaks first is the micro-habits: the quick rinse while the water heats up, the automatic second flush, the bottled water bought because the tap tastes weird and you're too tired to boil. To keep the habit alive, you need systems that require zero willpower on bad days.

One trick: pre-commit to a single non-negotiable. For me, it's the bucket-in-shower method — catch cold water while waiting for hot, use it to flush later. That one act anchors the rest. When I skip everything else but still do the bucket, the trip feels earned. Most teams skip this step; they try to maintain ten rules and drop all ten by Thursday. Better to pick one low-effort ritual that costs nothing and makes you feel slightly smug. That smugness — honestly — is fuel.

The psychological cost of constant vigilance

Eco-fatigue is real. It whispers that your liter-per-day savings don't matter when the resort next door drains a swimming pool nightly. The catch is that you're not trying to offset the resort; you're training yourself to live lighter, trip after trip. But the mental overhead of tracking every tap, every bottle, every laundry load — it grinds. I have felt it mid-trip in Marrakech, staring at a shower head that took three minutes to warm up, calculating whether the wasted water justified skipping hygiene. That hurts.

The trade-off: constant vigilance produces diminishing returns. After a certain point, the next liter saved costs disproportionate mental energy. You have to decide: is this a game, or is this penance? If it feels like punishment, you'll revert. The fix is to build slack into your system. Allow yourself one “water-blowing” moment per trip — a long shower, a pool dip, whatever — without guilt. That release valve keeps the rest of the trip sustainable. Without it, the whole practice collapses.

Tools and apps that help track and remind

I am not an app person. Most of them want to gamify everything until you resent the notifications. But I found one trick that stuck: a simple timer on my phone labeled “Shower ⏱️” — four minutes, hard stop. The alarm tone is obnoxious. It works. A friend uses a reusable water bottle with tick marks for daily refills; she counts them at dinner and adjusts next day. That's the level of tech you need — not dashboards, not carbon calculators, just a nudge that interrupts autopilot.

What about offline? A crumpled sticky note on your toiletry bag: “How many liters today?” I saw this in a guesthouse in Nepal — the owner had written it in permanent marker on a mirror. Crude. Effective. The point isn't the tool; it's the pause it forces. One rhetorical question worth asking: If I can't remember my last decision about water, when did I stop deciding? That pause — two seconds — is what separates drift from intention.

“The habit that breaks first is the one that never got automated. The rest is just excuses dressed as tiredness.”

When Not to Use This Approach: Destinations Where Water Conservation Is Futile

Places where tourism water use is dwarfed by industrial agriculture

You're sipping a filtered bottle in your guesthouse in Almería, Spain, feeling guilty about that extra rinse cycle. Meanwhile, just outside town, a single greenhouse complex covering 1,000 hectares pumps more groundwater in a morning than the entire local hospitality sector uses in a month. That's not hyperbole — it's the geometry of scale. The tomato on your sandwich probably drank 50 liters to get here. You, brushing your teeth for two minutes, used maybe two. The catch is personal: eco-guilt is a terrible compass when your footprint sits inside an industrial shadow ten times larger. I have stopped hauling my own filter straw to places like the Canary Islands or California's Central Valley. Why? Because the elephant in the room is plastic-wrapped and sitting in a refrigerated truck. Your solo trip's water habit is a rounding error against agricultural irrigation. That doesn't mean waste is fine — it means you should ask: "Is this a guilt problem or a systems problem?" Usually the latter.

All-inclusive resorts with their own desalination

Here's the weird paradox. You book a budget room in a small Moroccan riad — and suddenly you're wrestling with shower timers and greywater buckets. Meanwhile, the resort two blocks away runs three swimming pools, a water park, and a golf course, all powered by an onsite desalination plant that literally turns seawater into a river. Your conservation effort there? Pointless. Not ethically wrong — just mechanically irrelevant. The desal unit doesn't care if you take a 3-minute shower or a 30-minute one; it runs at a fixed capacity, producing a fixed volume, and the excess either gets dumped or used for landscaping. I learned this the hard way in Cancún. Spent a whole week taking military showers, skipping laundry, reusing towels — only to watch the hotel's sprinklers drench the palm trees at 3 PM every day. The tricky bit is knowing which bucket you're in. If the resort's water comes from a municipal supply shared with local residents, conserve. If it's desalinated or treated wastewater recycled on-site? Relax. Your individual valve-twiddling doesn't shift the mass balance.

Destinations where water scarcity is seasonal and your impact is negligible

Some places dry out for four months and flood for the other eight. Monsoon regions, snowmelt-fed valleys, high-altitude sites with annual freeze-thaw cycles — these aren't perpetual water crises. They're rhythmic. Show up in the dry season and yes, every liter matters. Show up in the wet season and your consumption gets lost in the runoff. Most travelers miss this because they google "water scarcity [place]" and get a static warning, not a hydrograph. The pitfall is overcorrecting: arriving in, say, northern Thailand during the rainy season and treating every bucket like it's a drought. That's performative austerity — it doesn't help anyone and it makes your trip worse. What usually breaks first is your motivation. You start policing yourself on a day when rain is hammering the roof and the river outside is visibly rising. That hurts — it trains your brain to see conservation as theater. So here's the rule I now use: check the monthly rainfall data, not the annual average. If your month's precipitation exceeds your entire trip's water use by a factor of 100, shift your focus elsewhere. Not to waste — to the things that actually matter. Water quality. Bottled plastic. The fact that your hotel's pool filter probably wastes more than your tap ever will.

If your month's precipitation exceeds your trip's water use by a factor of 100, shift your focus elsewhere — not to waste, to what actually matters.

— personal rule, refined after a guilt-heavy week in Chiang Mai during monsoon

Honestly — the hardest part is admitting when your effort is cosmetic. I wasted months of mental energy on shower timers in places where it didn't move the needle. Now I use that same energy to avoid destinations where my conservation would actually matter — places like desert oases, small islands without desal, villages dependent on a single aquifer. Those are where your habits still carry weight. Everywhere else? Focus on the stuff that scales: trash, transport, the carbon cost of your flight. Your water footprint there is a ghost in the machine. Let it go.

Open Questions / FAQ: What Solo Travelers Actually Ask

Is it better to skip the hotel laundry or wash clothes in the sink?

Most solo travelers assume sink-washing is the eco-choice. Wrong order, often. A hotel's industrial laundry machine uses roughly 15–25 gallons per load—but it's handling 50+ kilos of towels and sheets. Your single shirt in a sink? That's 3–6 gallons of hot water running while you scrub, rinse, rinse again. The trade-off is brutal: you're using more water per garment, and you're likely dumping detergent suds straight into municipal drains that don't treat greywater. If the hotel reuses towels (most do), let them handle it. If you're in a true drought zone—say a coastal village in Portugal where residents queue at tanker trucks—then sink-wash only if you catch the cold water in a bucket for the toilet flush. That sounds obsessive. It's. That's the point of solo travel in stressed regions: your habits either fit the local hydrology or they don't.

Does flying or staying in a water-scarce region matter more?

The knee-jerk answer is "flying"—one round-trip flight can emit 1–2 tons of CO₂. But water isn't carbon. A 10-day solo trip in a severe-drought region can consume 200–400 gallons through showers, laundry, and food preparation (the hotel's kitchen water footprint gets assigned to you). That's drinking water the community doesn't have. Flying, for all its emissions, doesn't drain a specific village's aquifer. The catch is they aren't separate problems—you flew to the water-stressed place. I have seen travelers brag about skipping one bed-sheet change while booking a second flight to a desert festival. That's performative, not strategic. A better metric: don't fly to a water-scarce destination unless you're prepared to use ≤25 gallons per day across all activities. Check the baseline. If you can't commit to that, pick a region with seasonal abundance.

'I stopped washing my hair for a week in Cappadocia. Then I realized the hotel refilled the pool daily. I was saving thimbles while they were dumping bathtubs.'

— overheard at a hostel in Goreme, 2023

How do I find out a destination's water stress level before I go?

Skip the generic "water scarcity map" apps—they aggregate at country level, which is useless. Southern Spain's Costa del Sol has plenty; Almería province two hours north is practically a dust bowl. What actually works: open the local water utility's website (search empresa de aguas + city name) and look for their supply bulletin. Many Spanish and Greek utilities publish weekly reservoir levels. If that's too bureaucratic, check hostel reviews for phrases like "shared showers timed," "water supply cuts," or "truck delivered water." That's not a bug—it's locals managing scarcity. Alternatively, search Twitter/X for the city name + "water restrictions 2025"—local journalists post specific bans (e.g., "no filling pools," "no washing cars," "public showers closed"). The Aqueduct Water Risk Atlas by WRI is fine for research, but it won't tell you if your guesthouse has a 50-liter hot water tank. Call ahead. Ask: "Is there a limit on shower duration or laundry?" If they laugh, you're fine. If they pause, you've got your answer.

One more thing—don't trust third-party "sustainability" badges on booking sites. I have stayed at a "Eco-Friendly" hotel in Morocco that changed sheets daily and ran a leaky sprinkler all afternoon. The real data? Ask the person at the front desk. Most will tell you honestly if they're under restrictions. That conversation alone can save you 150 gallons over a week. Try it. The worst they say is "no restriction." The best? They hand you a bucket and a timer. That's not a downgrade. That's an invitation to travel like the locals do.

Summary + Next Experiments

Three small changes to test on your next trip

Let's skip the grand resolutions. Instead, pick one experiment for your next solo outing. The shower timer trick: set a 3-minute playlist on your phone—no skipping tracks, no rewinding. I've watched this single shift cut my water use by nearly half at hostels where the timer already ticks against you. Next: the 'sink basin' rule. Fill the sink once for washing dishes, face, or clothes; never let the tap run. It sounds absurdly small until you've done it for a week and realize how much water you'd been burning on idle rinsing. Third, carry a reusable bottle with a built-in filter—not for virtue, but because it stops you buying plastic bottles whose production footprint dwarfs your shower. The catch? Each of these requires you to break a muscle-memory habit on day one. That hurts. But by day three, it's just how you travel.

How to measure your own water footprint

You can't manage what you don't, well, guess at. Most solo travelers overshoot because they have zero awareness of their per-day consumption. A rough field method: before your trip, fill a 1-liter bottle. Every time you use water—shower, wash hands, brush teeth, cook—pour that imaginary liter back into the bottle in your mind. Weird? Yes. Effective? Also yes. I once did this on a three-week trip through Morocco and discovered my 'quick' showers were actually running 8–10 liters. The fix was simple: wet down, turn off, soap up, rinse on. That one change saved roughly 60 liters over the trip. The trade-off is you'll feel slightly neurotic for the first two days. But neurotic beats ignorant when you're camping near a spring that serves an entire village.

Share your findings: start a conversation with other travelers

Post your experiment results somewhere real—not for applause, but for calibration. Hostel common rooms, traveler forums, even a scrawled note on a bulletin board. I once saw a solo hiker in Patagonia pin a hand-drawn chart comparing shower lengths across the camp. That sparked two days of people challenging each other to beat the 2-minute mark. What usually breaks first is the ego: you'll realize your 'low-impact' habits aren't as low as you thought. The pitfall? Don't turn this into a competition that breeds guilt or one-upmanship. The point is curiosity, not virtue signaling. So try one change, measure the result, tell someone else what you found. Then try another. That's it. No manifesto needed—just a willingness to be slightly uncomfortable for a few days and see what shifts.
