Each Trial is a strategy a real species uses, turned into something you can run yourself in about ten minutes. Each card says what to do and why it helps.
What each Trial asks you to do, and what it does for you. Reading a Trial needs no account. 3,017 Trials across 2,325 species. Showing 421–480.
The Trial
Take something useful you learned in one part of your life and deliberately carry it into an unrelated one today: a method from work into the kitchen, something from a hobby into a meeting. Apply it there, out loud, and say where it came from.
Why it helps
You keep what you know in separate boxes, so the same problem gets solved badly twice. Carrying a method across is free and it is usually the fastest improvement available to you.
2 minDifficulty 1
The Trial
Bring everything you gather today back to one store rather than using any of it where you found it, and add it all before stopping.
Why it helps
Using things where you find them means nothing accumulates and every lean week starts you at zero. Carrying it all back is what turns ordinary days into a reserve.
2 minDifficulty 2
The Trial
Take the small items you would normally pass on one at a time. Collect them all day today without sending any, then deliver the whole accumulated batch in one go at the end.
Why it helps
Passing small things on the moment you have them interrupts the other person constantly and makes each item feel urgent. One accumulated delivery costs them a single interruption for all of it.
2 minDifficulty 1
The Trial
Take something you left with someone else or in another system and bring it back under your own control for one step: the draft you handed over too early, the decision you deferred, the task in someone else's queue. Take it back and move it yourself today.
Why it helps
Things you hand off too early develop at whatever pace that queue runs, which is rarely yours. Taking one back and moving it yourself costs an hour and unsticks what had been waiting weeks.
2 minDifficulty 1
The Trial
Take something you are constantly carrying in your hands or holding in your head and move it onto your body or into a system instead: the pocket, the strap, the written list, the reminder. Free the hands today.
Why it helps
Holding things in your hands or your head uses the exact capacity you need for the work. Moving the load somewhere that holds it gives that capacity straight back.
2 minDifficulty 1
The Trial
Take the thing you keep leaving at home or at your desk and then needing, the notebook, the charger, the medication, the water, and attach it to what you actually carry. Show it in its usual abandoned spot, then physically fixed to your bag or keys.
Why it helps
Anything kept in a safe place is only there when you are. Attaching it to what you always carry means you stop rediscovering that you need it when you are somewhere else.
2 minDifficulty 1
The Trial
Choose one bulky but manageable object that genuinely needs moving and carry it across the room with deliberately smooth posture. Put it exactly where it belongs.
Why it helps
Combines useful work with posture, composure and control under an awkward load.
10 minDifficulty 2
The Trial
Seal one raw egg in a zip bag and tuck it inside a snug top against your chest. On a clear floor, walk five slow figure-of-eight laps round two chairs in one room, sitting down on one chair and rising again twice along the way, then take the egg out.
Why it helps
A few slow, careful minutes that sharpen balance and body awareness.
8 minDifficulty 1
The Trial
Set four broad stable objects close together on a table and move one coin across them using a flat card that must touch each support in order.
Why it helps
You turn floating balance into one concrete, visible experience instead of an abstract idea.
10 minDifficulty 2
The Trial
Carry one safely manageable heavy bag or loaded backpack for ten deliberate steps, then set it down under control.
Why it helps
Provides a short strength challenge with a concrete finish and controlled effort.
3 minDifficulty 3
The Trial
Pack three to five kilograms, such as filled water bottles, into a backpack that sits comfortably, and arrange a helper or a second device, such as a tablet on a self-timer, to take the finish photo. Start a walk-tracking app and walk one kilometre on a park or footpath route with no road crossings, at a calm pace you could keep for an hour, without stopping or sprinting.
Why it helps
A calm, weighted walk that shows how steadily you can carry a load.
15 minDifficulty 1
The Trial
Pack a small lunch at home, go on a safe route you already use to open public grass away from home within about five minutes' walk, such as a green, park or field (not your own garden), eat it sitting out in the open, then pack every wrapper back into your bag and carry it all home.
Why it helps
A lunch break outside instead of at a desk, and a short walk each way.
20 minDifficulty 2
The Trial
Stand side by side with a partner and trap one sheet of paper between your touching shoulders. Walk a figure-eight around three chairs set in a row and back to the start without either of you touching the paper with your hands.
Why it helps
A giggly coordination game that makes two people move as one.
10 minDifficulty 2
The Trial
Move one small useful object across a room using your body or clothing but not your hands. Finish with the object where it genuinely needs to go.
Why it helps
You discover how much your body can carry when your hands are not allowed to.
10 minDifficulty 2
The Trial
Wrap a small harmless object in cloth and keep it attached to your belt, pocket or bag for ten minutes while doing an ordinary quiet task.
Why it helps
You turn paternal care into one concrete, visible experience instead of an abstract idea.
10 minDifficulty 1
The Trial
Tear ten strips from paper or an old cloth and tuck them into the back of your waistband. Walk across the room to a shoebox or bowl, then pull them out one at a time and weave them into a nest cup.
Why it helps
A calm little build that ends with something cosy to look at.
15 minDifficulty 1
The Trial
Bring with you today the one thing a place cannot supply, and stay there for a set period without going back out for it.
Why it helps
Going back out for the thing a place does not have means you never settle into it and lose the time twice. Bringing it with you lets you simply stay.
2 minDifficulty 1
The Trial
Find the item in your group that is too big for anyone to pick up and move it a real distance today, even without finishing it. Say where it got to.
Why it helps
The oversized item sits untouched for months blocking everything behind it, because everyone takes the small ones. Moving it a real distance makes you the person who unblocked the thing.
2 minDifficulty 1
The Trial
Find one way today to carry or hold something using a capacity you were not counting on, keeping your main capacity free for the main job.
Why it helps
Using your main capacity to carry things means it is unavailable for the work. One secondary capacity frees it entirely.
2 minDifficulty 2
The Trial
Prepare two or three different presentations today for a situation with no retreat available, and actually switch between them as it changes.
Why it helps
One presentation in a situation with no retreat means being read and cornered. Two or three switched between keeps you workable wherever it goes.
1 minDifficulty 3
The Trial
Take one idea or method you picked up from somewhere. Deliver it today into a context well away from where you got it, and name both the source and the new place.
Why it helps
Using what you learn only where you learned it means it adds nothing, because that place already has it. Carrying it somewhere distant is where the same thing becomes genuinely valuable.
2 minDifficulty 2
The Trial
After finishing something today, clear the debris it produced immediately rather than later: the packaging, the temp files, the draft versions, the open tabs. Do it as the last step of the task, not as a separate job.
Why it helps
Debris left behind is what makes the next task start in a mess and what tells everyone what you were doing. Clearing it as the last step costs two minutes and the next start is clean.
2 minDifficulty 2
The Trial
Carry what is needed to one thing today that should not be moved, making the trip yourself rather than relocating it.
Why it helps
Moving something fragile to where the resource is exposes it for the whole journey. Making the trip yourself and bringing the resource keeps it where it was safe.
2 minDifficulty 2
The Trial
Find the thing you keep going somewhere else to do and build a sealed portable version you can carry: a pouch, a tin, a small kit with everything in it. Show the trips you were making, the kit assembled and closed, then the thing done somewhere new.
Why it helps
If a task needs a particular place, it only happens when you are there. Making the conditions portable means it happens in the gaps, and the gaps are where most of your time actually is.
2 minDifficulty 1
The Trial
Choose one job that needs several things moved, such as laundry to the machine, shopping into the cupboards or a bag for tomorrow. Gather every item first, then move it all from start to finish in one continuous trip at a steady walking pace. Do not go back for anything.
Why it helps
You lose time and focus going back and forth for things you forgot. Gathering everything first and moving once trains you to plan ahead, so bigger changes later go in one clean go.
2 minDifficulty 2
The Trial
Move one thing across a boundary today, a department, a discipline, an altitude of seniority, rather than further within its own band.
Why it helps
Moving something further within its own band changes nothing about who sees it. Crossing one boundary puts your work in front of people who never would have.
2 minDifficulty 2
The Trial
Mark a sheltered spot, such as under a bench or hedge, and a patch of fallen leaves or grass clippings at least ten steps away. Make twenty trips, each carrying one two-handed handful back to the pile, and give a short sharp call each time you drop a load.
Why it helps
A brisk garden job with a satisfying heap at the end.
15 minDifficulty 2
The Trial
Mark a trail with tape along the floor from a scrap-paper pile to an empty box about four metres away, clearing anything that sits on it. Tear the paper by hand into twenty palm-size pieces and carry them one per trip along the trail, laying each flat on top of the last in the box.
Why it helps
A gently rhythmic job that clears scrap paper and shows how small repeats add up.
12 minDifficulty 2
The Trial
Find the task on your team or in your household that is stuck because it is too big or awkward for anyone else to pick up, and take that one specifically. Move it a visible distance today rather than finishing it.
Why it helps
Everyone picks up the small tasks, so the big awkward one sits for months blocking things behind it. Taking the load only you can carry moves what nobody else could.
2 minDifficulty 2
The Trial
Identify one thing that will not happen unless you do it, because nobody else is positioned to. Move it forward one concrete step today, and leave the things others could do for them.
Why it helps
Spending your day on work others could also do means the one thing only you can move never moves at all. Finding it and taking a step is the part of your effort nobody can replace.
2 minDifficulty 2
The Trial
Identify one condition you tolerate that visibly stops other people, the early start, the mess, the ambiguity, and deliberately take on something today specifically because it sits in that condition.
Why it helps
Competing on ability puts you against everyone good at the same things. Taking the work that sits in a condition others will not tolerate means it is simply yours.
2 minDifficulty 1
The Trial
Use cardboard, foam, cork or another easy-to-work scrap to cut or press a fitted slot for one small object you keep misplacing. Stop when the object sits securely inside it.
Why it helps
You turn scrap into a custom holder and give one loose object a permanent home.
12 minDifficulty 1
The Trial
On a tablecloth, towel or rug, spread twenty playing cards face down in a straight, evenly overlapping ribbon. On go, lift the edge of the end card and push it over so the whole line flips face up in one running wave, succeeding within five tries and two minutes.
Why it helps
A slick little card flourish that feels brilliant when the whole line goes.
5 minDifficulty 4
The Trial
Sit on a sturdy chair holding five loosely crumpled tissues. On go, toss one straight up, spring up to catch it before it lands, sit back down and repeat until all five are caught, within thirty seconds.
Why it helps
A quick, bouncy burst that wakes up your legs and reflexes.
3 minDifficulty 3
The Trial
Place a jug under the hot tap before you turn it on. Catch all the cold water that runs until it turns warm, then turn it off and use the jug to water a plant, rinse dishes or fill a mop bucket, not for drinking or the kettle.
Why it helps
Water saved without effort and a jug of plant water ready to use.
5 minDifficulty 1
The Trial
Stay seated and have someone toss one soft object toward you from an unpredictable angle. Catch it with both hands without standing or leaving the seat.
Why it helps
A quick burst that is genuinely fun to land and takes under two minutes to set up.
15 minDifficulty 4
The Trial
Sit tucked in a nook, such as the corner of a sofa or beside a bookcase, with a line of tape marking your reach. A consenting helper rolls ten soft balls or rolled socks slowly past at random, and you catch only those that cross the tape.
Why it helps
A calm patience game that is surprisingly hard to resist.
8 minDifficulty 1
The Trial
Before your next shower, put a jug or bowl under the shower head or tap. Catch all the cold water that runs while you wait for it to warm, then move the jug aside before you get in. Use the caught water straight away to water a plant or fill a watering can.
Why it helps
You waste more than you notice while waiting for the perfect supply to arrive. Catching the small flow you usually let go gives you something useful from what you already pay for.
2 minDifficulty 1
The Trial
Have a consenting person drop three soft, unbreakable objects one at a time from just above your reach. Catch each before it touches the floor.
Why it helps
You turn rising strike into one concrete experience with a visible finish.
5 minDifficulty 3
The Trial
Have someone release twenty small paper scraps above a clear table while you sweep as many as possible into one wide container in a single pass.
Why it helps
You turn dusk harvest into one concrete, visible experience instead of an abstract idea.
10 minDifficulty 2
The Trial
An organiser hides ten tokens together in one spot in a garden or park area and lays a blanket as the roost. At least three people start on the roost and fan out in different directions; the finder gives a loud caw without touching the stash, everyone else must reach it within twenty seconds, and then the whole flock carries the tokens back to the roost.
Why it helps
A fast, cheerful group game with a real feeling of teamwork.
10 minDifficulty 2
The Trial
Take something you keep carrying along manually and attach it permanently today to a process that is already running: the recurring meeting, the automated step, the existing checklist.
Why it helps
Carrying something along manually means it stops the week you forget. Attaching it to something already running means it continues without you.
2 minDifficulty 2
The Trial
Permanently commit one thing today that will never need to move again, and spend everything else on collecting from the flow.
Why it helps
Keeping everything movable means you spend effort maintaining that option instead of collecting. Permanently fixing one part frees all of it for you.
1 minDifficulty 4
The Trial
Prepare one specific place today where what you do reads correctly, and perform there rather than wherever you happen to be.
Why it helps
Performing wherever you happen to be means the same effort lands differently every time. One prepared place means it reads correctly every time.
1 minDifficulty 4
The Trial
Begin one change today that the coming conditions will require, before those conditions arrive, and state which signal told you it was coming.
Why it helps
Starting a change when the conditions have already arrived means weeks of being wrong for them, which is exactly when it costs. Starting on an early signal means you are ready.
2 minDifficulty 1
The Trial
Change one presentation today because you have outgrown it, rather than keeping it until it visibly stops working.
Why it helps
Keeping a presentation until it visibly fails means being caught in it at the worst moment. Changing it when you outgrow it is quiet and costs nothing.
2 minDifficulty 2
The Trial
Change one exact control point today rather than the whole system: the single setting, the one sentence, the one person's decision. Change it fast and change nothing else.
Why it helps
Changing everything when something is wrong means you cannot tell what worked and you break things that were fine. One exact change tells you what actually controls it.
1 minDifficulty 3
The Trial
Take something you believe takes a long time to change, a habit, an opinion, a process, and run a deliberate two-week version of it starting today. Set the end date and the one measure you will check.
Why it helps
Assuming change takes years is why you never start. A deliberate two-week test with one measure tells you the real timescale, and it is usually far shorter than you assumed.
2 minDifficulty 2
The Trial
Choose one harmless visual detail in your clothing, desk, profile or room that feels like an older version of you and change it once to something that fits you better today. Do not buy anything for the change.
Why it helps
You mark growth by deliberately leaving one old signal behind instead of carrying every past version forward.
10 minDifficulty 1
The Trial
Write the objective down first today, then change your approach as much as conditions require without altering the written objective.
Why it helps
Changing your approach without a written objective means the goal quietly drifts with it. Writing it first lets you be as flexible as you like.
1 minDifficulty 3
The Trial
Name one move you are planning into a genuinely different environment. Identify the one thing about how you currently operate that will not work there, and change that one thing today before going anywhere.
Why it helps
Walking into a new environment with the habits of the old one means you fail there for reasons you read as the place rejecting you. Changing the one incompatible thing first is what makes the move survivable.
2 minDifficulty 2
The Trial
Keep the same working tempo today through a changed condition, and adapt only your appearance to it: change the clothing, the tool, the surface you work on, but not the rate at which you work.
Why it helps
Slowing down whenever conditions change means you lose ground every season and never get it back. Changing only what shows keeps your output steady through the same conditions.
1 minDifficulty 4
The Trial
Name one task you have abandoned at least twice. Do not try harder at it. Instead change the ground: move it to the hour when you have most energy, remove the two things that stopped you last time, and shrink it to the smallest version that still counts. Then finish that version today, in one sitting.
Why it helps
If you keep failing the same task, more willpower is the expensive answer. Changing the conditions it happens in costs you nothing and is usually the whole reason it never got done.
2 minDifficulty 2
The Trial
Take a place or situation you avoid because your usual way of working does not suit it, and change one of your own settings to fit it instead: the hours, the format, the tool, the standard. Then go into it today.
Why it helps
Avoiding every situation that does not suit your defaults shrinks where you can operate, year by year. One adjustable setting usually opens a whole environment back up.
2 minDifficulty 2
The Trial
Set a sixty-second timer and change your look from the shoulders up until someone glancing over would not place you — past recognition, using hair, layers, glasses, whatever is within reach.
Why it helps
A fast, funny minute, and a genuinely useful discovery about what people actually recognise.
2 minDifficulty 4
The Trial
With at least two other people present, a helper rolls an orange across a lawn or long clear floor while you wait behind a line. Chase it down, then peel it and hand out every segment so each person, you included, holds the same number, all within sixty seconds of the roll; split any leftover segment by hand.
Why it helps
A fast, generous little game that ends with everyone eating.
5 minDifficulty 3
The Trial
In a garden or large clear room, a consenting helper rolls five soft balls or oranges in different directions at the same moment while you stand three metres behind them with a basket. On the release, chase them all down and put them in the basket within twenty seconds.
Why it helps
A short, all-out sprint that is pure play.
3 minDifficulty 4
The Trial
Roll a soft ball through a clear path while a partner makes harmless background noise; reach and stop the ball before it crosses the finish mark.
Why it helps
You turn crested pursuit into one concrete, visible experience instead of an abstract idea.
5 minDifficulty 3
The Trial
Take something you have been preparing one careful attempt at and instead make at least five cheap attempts today, accepting that most will return nothing.
Why it helps
Perfecting one attempt means one result and no information. Five cheap ones usually land something and tell you where the rest are.
2 minDifficulty 2
The Trial
Pick one decision you have been circling for days. Stop working on it. Set a time later today when you will decide, and until then do nothing about it at all - no research, no asking around, no drafting. At that time, decide in under two minutes and act on it immediately.
Why it helps
Circling a decision burns more of you than making it, and the extra information rarely changes the answer. Holding still until a set moment and then committing once gives you back days of low-grade dread.
