How can the regret minimization framework decide what goes on a Do It Tomorrow list?

And how Do It Tomorrow sharpens Regret Minimization Framework in return.

Do It Tomorrow decides when a task happens. It does not decide whether the task deserves to exist. That is the gap, and the regret minimization framework fills a narrow, specific part of it. Do It Tomorrow, from Mark Forster's book of the same name, works like this: anything that arrives today gets written onto a list for tomorrow rather than acted on now, and tomorrow's list is closed — a line is drawn under it and nothing new gets added once you start working it. Today's commitments stay intact, and the thing that arrived at eleven in the morning waits its turn. The regret minimization framework, the rule of thumb Jeff Bezos described using when he left a secure job in 1994, works at a different scale: you project yourself to age eighty, picture that person looking back, and ask which option they would regret. Put the second at the point of capture and you get a filter for the first — a short check, before you write something onto tomorrow's page, on whether this is something you would want to have done. The two operate at different moments and neither substitutes for the other. Nobody has tested them together.

What each one is actually for

Regret Minimization Framework

The regret minimization framework is for the choice you have been circling for weeks because both options are defensible. Rather than comparing the options on their merits, which is what you have already been doing without success, you move where you are standing. Project forward to eighty, put that person in the room, and ask which of these they would still be sore about. The interesting property is that the question tends to produce an answer quickly and with unusual confidence, because a lot of what makes a decision feel impossible in the present — the fear of looking foolish this quarter, the pull of the comfortable option this month — simply does not reach across decades and stops competing. It is a values-surfacing device disguised as a time-travel exercise. It is not a planning tool and it says nothing whatsoever about what you do next.

Do It Tomorrow

Do It Tomorrow is a working system for a day, built by Mark Forster around one rule that does most of the work: new tasks do not get done today. When something arrives — an email, a request, a thought — you write it on tomorrow's page and go back to what you were doing. Tomorrow, that page becomes a closed list: you draw a line under it, nothing else gets added, and you work it until it is finished. Because a closed list has a bottom edge, you can actually finish a day, which an ever-growing list makes structurally impossible. Two other pieces matter. Forster separates the backlog — everything already piled up before you started — and works it as its own project, so it does not silently poison every day's list. And for anything ongoing he uses little and often: a recurring small daily block, thirty minutes on the same thing every day, rather than waiting for the mythical free afternoon.

What you get out of pairing them

What Do It Tomorrow gives you is the end of the day actually arriving. A closed list can be completed, and completion is a feeling most people running an open to-do list have not had in years — the list they use is a list they are always losing to. What the age-eighty question gives you is a defence against the specific failure that a good day system cannot see: finishing everything on the list, every day, for a year, and arriving at the end of that year having done almost nothing you would have named on the first morning as mattering. Forster's system is scrupulously fair to whatever arrives. That is its strength and it is also the hole. A request from a colleague who is good at asking and a piece of your own work that nobody is chasing land on tomorrow's page with identical weight, and the one nobody is chasing is the one that quietly never gets written down at all. Adding a filter at the moment of capture buys you a list that is still finishable but is made of things you would defend, and it buys it for about thirty seconds a day.

What Regret Minimization Framework rests on

  • Self distancing improves judgment randomised trials
    Evaluating a situation from a distanced, third-person vantage point instead of an immersed first-person one improves the quality of judgment about it.
  • Long term framing surfaces values practitioner report
    Framing a decision against a long time horizon surfaces which option better matches a person's deeper values and cuts through short-term ambiguity.

What Do It Tomorrow rests on

  • Implementation intention closes intention action gap randomised trials
    Pre-committing to a specific situational cue paired with a specific response lets the behavior fire automatically when the cue occurs, without depending on in-the-moment willpower.
  • Closed lists reduce overwhelm practitioner report
    A fixed bounded list of tasks rather than an ever-growing open list reduces the felt overwhelm of an infinite to-do list.
  • Deferred capture protects commitment practitioner report
    Writing newly arriving tasks onto tomorrow's list rather than acting on them immediately protects today's already-committed plan from being derailed by reactivity.

Where they actually meet

Both practices distrust the person standing in the moment, and both buy their way out of it with time — just at wildly different scales. Forster's rule buys you one night. A task that arrives at eleven in the morning feels urgent partly because it just arrived; sleep on it and by tomorrow the urgency has usually either evaporated or turned out to be real, and either way you are choosing rather than reacting. The age-eighty question buys you decades, and it is aimed at a different distortion: not the false urgency of the last five minutes but the false weight of this whole season of your life, the job that feels permanent, the fear that feels final. There is a second thing they share which is easier to miss. Both convert something open-ended into something with edges. An infinite to-do list becomes a page with a line drawn under it. A sprawling life question becomes a single yes or no held by a specific imagined person. In both cases the material was the same before and after; what changed is that it acquired a boundary, and things with boundaries can be finished, whereas things without them can only be survived.

The principle underneath both

Judgment made from inside a moment is bent by that moment, and the reliable correction is not to think harder but to move the judging somewhere else in time. Forster moves it one day; the age-eighty question moves it forty years. What both are betting on is that the pressures distorting the view — this arrived just now, this feels enormous this year — decay quickly with distance, while the things you actually care about do not decay at all. Whatever survives the move is the more trustworthy signal.

What that makes the real goal

Getting your hours spent on things a calmer, longer-sighted version of you would have chosen, without having to become that person first. Stated that way the goal belongs to neither a time management system nor a decision heuristic, and you can go shopping for anything that serves it. Note that it has two halves that come apart: choosing well and then actually doing the chosen thing. A practice can be excellent at one and useless at the other, and most are.

Other practices that serve the same goal

If-then planning is the best-evidenced route to the second half. Deciding in advance that when a specific situation occurs you will perform a specific action — when I sit down after breakfast, I open the manuscript — has a large body of randomized-trial support for closing the gap between intending something and doing it, considerably stronger evidence than either practice on this page carries for itself. Forster's own little and often is essentially this in a daily wrapper. For the first half, a full week's time log — recording all 168 hours rather than estimating them — attacks the same problem from the measurement side: it does not tell you what matters, but it shows you unambiguously where the hours went, and the gap between the log and your stated priorities does the argument for you. The Eisenhower grid, sorting tasks by important against urgent, is the classic filter and is essentially practitioner lore rather than a tested method. And a decision journal — writing your reasoning and expected outcome at the time you decide, then rereading it a year later — serves the same objective in reverse, replacing an imagined eighty-year-old with a real record of what you actually thought.

A tradition that already does this

Benjamin Franklin's daily scheme, laid out in his autobiography, already fused these two moves. Each morning began with a written question — what good shall I do this day — and the day's plan was drawn up from the answer, in fixed blocks, before the day's demands arrived. Each evening closed with the matching review. The structure is a list made in advance from a values question rather than assembled from whatever showed up, which is what a capture filter and a closed list produce between them, arrived at two and a half centuries earlier with neither name attached.

Using the Regret Minimization Framework to enhance Do It Tomorrow

Put the filter at the exact point of capture — the moment your pen is already on tomorrow's page. Not everything gets filtered, and this is the part people get wrong: small operational items, reply to the plumber, order the cartridges, pay the invoice, go straight onto the list unexamined, because an eighty-year-old has no view on which afternoon a cartridge was ordered and asking wastes the thirty seconds. Apply the question only to arrivals that would either take more than about an hour or commit you to something ongoing. For those, ask it in its compressed form before you write: would the person I am at eighty regret not having done this, or would they not remember it happened. Then act on the answer immediately, because a filter you apply and ignore is worse than none. If it survives, it goes on tomorrow's page as normal. If it does not, decline it now, in one line, while the request is fresh and declining is cheap — and this is the specific move worth adopting: write the declined item at the bottom of tomorrow's page anyway, under a short rule, so it is visible. At the end of a week you have a list of everything you said no to. Most people have never seen that list, and it is far more informative than the list of what they did. If it is full of things you feel relieved about, the filter is calibrated. If it is full of things you wish you had kept, the filter is running too hot and you should widen it, which you could not have known without the record.

Using Do It Tomorrow to enhance the Regret Minimization Framework

The regret question has a well-known ending and no follow-through: it produces a verdict — take it, leave, start, stop — and then simply stops, at the exact moment when the verdict needs to become an action. Two of Forster's pieces close that gap, and they close it differently. First, the deferral itself works as an overnight test. A verdict reached at eleven at night is not acted on at eleven at night; it goes onto tomorrow's page as a line item, and a resolution that has evaporated by morning was arousal rather than clarity, which is worth learning cheaply. Second, and this is the one that actually matters over a year, use little and often rather than a single heroic step. A regret-tested decision is almost never one action. It is a novel, a career change, a repaired relationship. Written as a single task — write the book — it will sit on tomorrow's list being rewritten onto the day after for months, which is how a genuinely clarifying decision dies quietly without ever being reversed. Written Forster's way it becomes a recurring daily line of a size you would not skip: manuscript, thirty minutes. It goes on every day's list, including the bad days, especially the bad days. The clarity the age-eighty question produced was never going to survive on its own; a fixed daily block is what carries it, and it is the difference between having decided something and having done it.

The request that lands in your inbox at eleven in the morning

A colleague you like asks you to join a side project. It is interesting, it is flattering, and they need an answer by Friday. Everything in the moment is pushing toward yes on the spot: the enthusiasm in their message, the fact that you are already thinking about it instead of the thing you sat down to do, the small social cost of taking three days. So you do not answer. You write decide on side project onto tomorrow's page, and you go back to today's closed list, which is the whole of what Forster's rule asks of you and takes four seconds. The next morning it is sitting there among nine other items, at normal size, with none of yesterday's atmosphere around it. Now you run the other question, because this one qualifies — it commits you to months, not an hour. At eighty, looking back, do you regret not having done this, or do you not remember it. And the answer arrives faster than you expect and is not the one you would have given yesterday at eleven: you would not remember it. What you would remember is the thing you have been failing to start for two years, which is not on any list because nobody has ever asked you for it. So you decline the side project in three sentences, write it under the rule at the bottom of the page where you keep the declines, and then write the other thing on tomorrow's list, as thirty minutes, every day, starting tomorrow.

When this is worth reaching for

The system is working and the year is not. You finish your list most days, you are not behind in the way you used to be, and you still arrive at December having done almost nothing you would have named in January as the thing that mattered — which is a specific and disorienting kind of failure, because none of the individual days went wrong. That is the condition this addresses. A second: the last few large commitments you took on were all agreed within an hour of being asked, and you can name at least two you would take back. A third, more mundane and probably more common: you already run a closed list faithfully, and the item you actually care about has been carried forward from yesterday's page to today's page for eleven days running, without ever being refused. Not yet, though, if you have only just started deferring tasks. Get the plain habit steady for a few weeks first; adding a values check to a capture rule you are not reliably following gives you two things to fall off at once.

Where this does not apply

Most of what lands on a working list should never meet this question. The regret minimization framework was built for choices with real weight and a long horizon — a career, a city, a relationship — where imagining yourself at eighty gives a meaningfully different answer from the immediate pull. Run it on reply to this email, order this supply, book the dentist, and you slow a fast system down for nothing, since your eighty-year-old self has no opinion about which afternoon the supply order went out. Worse, applied to everything it becomes a way of not doing the ordinary work, dressed as depth. For the bulk of a daily list, Forster's rule on its own is doing the job, and it is doing it well. There is also a class of task the question actively misjudges: obligations to other people. Small kindnesses, a check-in call, covering for someone — an imagined eighty-year-old summing up a life often rates these at zero, and they are frequently the thing that mattered most to somebody else. Do not let a filter aimed at your own regret quietly delete your commitments to other people. And if you are dealing with a genuine backlog, Forster's own advice stands and this does not change it: handle the backlog as a separate project rather than trying to filter your way out of it.

What the evidence does and does not support

The two halves of this page are not evidenced to the same standard, and it is not close. The move of standing outside a situation to judge it — evaluating a choice as an observer rather than from inside it — has been supported in randomized experiments on judgment and emotional distance; that research is about psychological distance in general and was never run on the age-eighty framing specifically, which is a heuristic a business figure described using and which has never been trialed as a method. Do It Tomorrow is in a similar position for a different reason. Forster's claims about closed lists and next-day deferral come from a practitioner writing up what worked for him and for people he taught, not from controlled comparison against other systems; the mechanism his follow-through depends on, deciding a specific action in advance and attaching it to a specific moment, is separately one of the best-replicated findings in behaviour-change research, which lends the system's spine some support that its particular rules do not have. Nothing tests the combination. A real test would need two groups running the same closed-list system for months, one applying a values filter at capture and one not, with someone counting a year later what each group had actually finished — and the outcome that matters, whether you regret the year, is close to unmeasurable in a trial, which is probably why nobody has tried.
