Using Possible Selves Exercise to enhance Time Smart
And how Time Smart sharpens Possible Selves Exercise in return.
The Possible Selves Exercise has you write out, in specific and sensory detail, the person you hope to become and the person you fear becoming — not 'healthier' but 'the version of me who cooks dinner instead of ordering in, three nights a week' — because a vague hope rarely motivates anything, while a vivid, particular image does. Time Smart asks a narrower, more mechanical question: how much of your actual week is discretionary, under your own control, and when you're deciding whether to take on a task, a purchase, or a commitment, what is its real cost in hours of your one, non-renewable supply of time. The gap between these two is exactly where most people's hoped-for self quietly dies: they can picture the person they want to become in vivid detail and still spend the next Tuesday exactly as they always have, because nothing ever converted the picture into an actual claim on their calendar. Time Smart is what makes the possible self testable in hours rather than left as a feeling you visit and then set down again.
What each one is actually for
Possible Selves Exercise
The exercise asks you to sit down and write two short scenes, not lists of traits: one describing, in first person and present tense, a specific day lived by the version of you that things went well for — what you did first thing in the morning, who you talked to, how the evening ended — and a second describing a day lived by the version you're afraid of becoming if nothing changes. The point of the specificity is that 'I want to be more disciplined' motivates almost nobody, while 'I am the person who already went for the run before checking my phone' is concrete enough to actually miss when you fail to live it. Once both pictures exist on paper, the exercise has you name the gap between where you are now and each of them, which is what turns a vague wish into something with an actual direction.
Time Smart
Time Smart, developed from research by Ashley Whillans, starts from a single reframe: money spent buying back time — paying someone to do a task you dread so you can spend that hour elsewhere — reliably raises wellbeing, and most people underuse this lever because they treat time as if more of it will simply show up later. In practice it works by running any pending purchase or commitment through a time-cost calculation before you agree to it: not 'can I afford this in dollars' but 'what does saying yes actually cost me in hours I will not get back, and is there a version of this that trades money for time instead of the other way around.' It also has you score your own time affluence — how much say you actually have over your own hours in an ordinary week — as a number you track, not a feeling you assume.
What you get out of pairing them
A hoped-for self on its own is cheap to have and easy to abandon, because nothing about picturing it tells you where, specifically, in an ordinary Tuesday, it was supposed to come from. Time Smart supplies exactly that: a way to look at a week and see, in hours, where the possible self would have to be carved out of the actual one you're living, and whether the trade is one you're currently willing to make. Without it, the exercise produces a compelling story that never meets a calendar. And Time Smart on its own has the opposite gap — it's excellent at making any single purchase or commitment's time cost visible, but it has no opinion about which hours are worth protecting in the first place, only that protecting some is generally good for you. The possible self is what tells Time Smart's math which hours actually matter enough to fight for.
What Possible Selves Exercise rests on
-
Concrete goals outperform vague aspirations
observational studies
Specifying a concrete hoped-for or feared image of the future is more motivating and actionable than an abstract aspiration.
-
Future self continuity motivates present action
observational studies
Vividly imagining one's own future self increases psychological connection to that self and motivates present behavior aligned with it.
-
Gap awareness motivates change
plausible mechanism
Awareness of the gap between one's current self and a hoped-for or feared future self motivates action to close that gap.
What Time Smart rests on
-
Externalizing makes pattern visible
randomised trials
Putting an internal pattern into an external, structured form makes it visible and available for examination instead of remaining implicit and merely enacted.
-
Quantifying tradeoffs improves decisions
plausible mechanism
Converting a purchase or commitment into an explicit time cost makes its true tradeoff visible before the decision is made.
-
Time affluence increases wellbeing
observational studies
Having more discretionary control over one's own time independent of money is associated with greater wellbeing.
Where they actually meet
Both exercises take something that would otherwise stay implicit — a hazy sense of who you're becoming, a hazy sense of what a commitment actually costs — and force it onto paper in a form specific enough to argue with. Possible Selves does that to identity: instead of 'I should be more present with my kids,' you get an actual scene, an actual evening, that you either lived this week or didn't. Time Smart does it to a transaction: instead of 'this seems worth it,' you get an actual hour count you either have or don't. Different material, same refusal to let a fuzzy version of the truth stand in for a specific one.
The principle underneath both
A future you can picture in detail is easier to want than a future you can only describe in categories, and a cost you can count in hours is easier to weigh than a cost you can only sense as 'a lot' or 'not much.' Both practices convert something soft and easily rationalized — a hope, a maybe-it's-fine purchase — into something specific enough that you can actually check your own behavior against it, rather than trusting a feeling that will happily tell you whatever keeps you comfortable.
What that makes the real goal
Underneath both is the same aim: give yourself a standard specific enough that drift becomes visible instead of invisible. Most people don't fail to become who they hoped to become through one dramatic decision — they fail through a thousand small trades of an hour here, a commitment there, none of which felt significant in the moment, all of which added up to a week the hoped-for self never lived. Naming the self and pricing the hour are two halves of catching that drift while it's still small enough to correct.
Other practices that serve the same goal
Implementation intentions — deciding in advance 'when X happens, I will do Y,' rather than deciding in the moment — pursue a version of the same closing-the-gap work with strong randomized-trial support, though they work at the level of a single trigger rather than a whole identity or a whole week. Values clarification exercises drawn from Acceptance and Commitment Therapy ask a person to name what actually matters to them in concrete terms and then check daily behavior against it, with a solid clinical evidence base, and function almost identically to a possible-self scene without the future-facing framing. Zero-based budgeting for money, applying the same logic Time Smart applies to hours, has widely reported behavioral results in personal finance coaching, though with thinner controlled evidence than the time-affluence research it borrows its shape from.
Using the Possible Selves Exercise to sharpen Time Smart
Time Smart's time-cost calculation answers 'is this worth the hours' with a number, but the number alone can't tell you what to protect those hours for — it just tells you what any given hour costs, not what it's for. Write your hoped-for-self scene first, in enough sensory detail that you could describe the actual room you're in during it, and pull three or four specific, recurring activities directly out of that scene — not 'more family time' but 'the Tuesday dinner where everyone's actually at the table, no phones.' Those become the fixed points your time-cost math protects by default: any purchase or commitment that would eat into one of those specific windows needs to clear a noticeably higher bar than one that eats into an evening the scene never mentioned at all. Without this step, Time Smart optimizes for a generically 'better' week; with it, the week gets built around a particular life you actually wrote down wanting.
Using Time Smart to sharpen the Possible Selves Exercise
The usual failure of the exercise isn't disbelief — most people find their own hoped-for scene genuinely compelling when they write it — it's that the scene never gets checked against an actual calendar, so it stays a story you visit rather than a claim on your Tuesday. After writing the scene, run it through a time-cost calculation: name the specific recurring block of hours it would require each week, and then look at your current week and identify, honestly, which existing hours would have to be given up to make room for it. If the scene needs three protected evenings and your week currently has zero unclaimed evenings, that's not a failure of willpower — it's a real scheduling conflict the exercise on its own would never surface, and now you know exactly which existing commitment has to move, get cut, or get paid to disappear.
Sunday night, a scene you wrote three months ago, and a Tuesday you're about to fill
It's Sunday night and a coworker has just asked if you can take on a side project that would eat two evenings a week for the next quarter. Your first instinct is to say yes — it's flattering, it's a good opportunity, and in the moment two evenings sounds like nothing. Before answering, you pull up the possible-self scene you wrote three months ago: a specific Tuesday evening, cooking dinner with your partner while music plays, no phone on the counter, a scene you wrote because that particular ordinariness was what you were actually missing. You run the side project through a time-cost calculation and land on the honest number: it would consume exactly the two weeknights the scene depends on, for three straight months. The project is genuinely good. It is also, specifically and concretely, the thing that would make the Tuesday you wrote about impossible for a season. You decline, not because the opportunity is bad, but because you can now see precisely what it would cost against a version of your week you'd already written down wanting more than the opportunity.
When this is worth reaching for
A new commitment or purchase is on the table, and it isn't obvious yet whether it's worth the hours — that's the moment the possible-self scene gives the time-cost math something specific to weigh against, instead of a generic sense that free time is nice to have. Or you've written a hoped-for-self scene more than once and lived none of it, which is usually a scheduling problem wearing a motivation problem's clothes.
Where this does not apply
If someone is in a season with genuinely no discretionary hours to reallocate — caregiving for a new baby or a sick family member, working a second job to cover a shortfall — running a time-cost calculation against a hoped-for scene mostly produces guilt about a trade that isn't actually available to make right now. In that season, the honest move is to name the constraint plainly and set the exercise aside rather than force a comparison that will only confirm something already painfully obvious.
What the evidence does and does not support
Vividly describing a hoped-for or feared future self has observational support for increasing motivation and psychological connection to that future self, though the underlying mechanism is still argued over rather than settled by a large trial base. Time Smart's core claims — that people underinvest in buying back time and that discretionary time control predicts wellbeing — rest on a mix of observational survey data and a smaller set of experiments on time-versus-money spending choices. No study has tested writing a possible-self scene together with running a time-cost calculation as a combined intervention; this page connects two separately supported ideas rather than reporting evidence for the pairing itself.
