Can You Set an Ambitious Stretch Goal and Still Use a Closed Tomorrow List?

What each one is actually for

Do It Tomorrow

Do It Tomorrow, developed by productivity writer Mark Forster, is built around a single mechanical rule: when a new task arrives today — an email, a request, an idea you have in the shower — you do not add it to today's list and you do not act on it immediately. You write it on a separate list reserved for tomorrow. Tomorrow, that list becomes fixed and closed: you work through exactly what's on it, in order, and anything that arrives during that day goes onto the list for the day after, never onto today's. You can picture doing this literally: two physical lists, today's and tomorrow's, and a rule that nothing crosses from the second into the first no matter how urgent it feels in the moment.

Stretch Goals

A stretch goal is a claim about method, not about workload, and that distinction matters more than it sounds. The target is set past what your current way of working can produce — a sales rep who has hit the same number three years running by working the same accounts, handed a figure forty percent higher, cannot get there by making more calls in the same pattern — and it is set there deliberately, because a target you could reach by simply doing more of what you already do invites exactly that, more of the same, while a target you plainly cannot reach that way forces you to go find a different pattern. Which means the honest response to a stretch goal is never a longer working day. Volume is the one lever it is specifically designed to render useless, and reaching for it first is the standard way people spend a year on a stretch target and arrive with the old method and no sleep. What has to change is which work exists at all: the search for an approach you do not have yet needs room that a full, well-run day of familiar tasks does not leave anywhere.

What you get out of pairing them

Run a stretch goal without something like Do It Tomorrow underneath it and you get a specific, predictable failure: the goal generates new ideas and new tasks faster than a normal day has capacity for, each one feels urgent because it's tied to the big ambitious thing you're chasing, and your actual committed work for today gets bulldozed by a stream of half-formed responses to the stretch goal. Do It Tomorrow gives every one of those a guaranteed landing spot — tomorrow, in order — without losing them and without letting them detonate today. You get to keep chasing the big number and still finish what you told yourself you'd finish today, because the two are no longer competing for the same hours.

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.

What Stretch Goals rests on

• Difficulty drives strategy search observational studies
  Setting a goal beyond current comfortable capability forces a search for novel strategies rather than incremental effort on existing ones.
• Goal difficulty raises effort and performance randomised trials
  Within the limits of ability and genuine commitment harder specific goals produce higher effort and performance than easy or vague goals.
• Stretch goals increase outcome variance observational studies
  Setting goals beyond current capability raises the spread of outcomes producing both more breakthroughs and more outright failures than moderate goals.

Where they actually meet

Both methods work by fixing something in place ahead of time so a decision doesn't have to be remade under pressure. Do It Tomorrow fixes where a new task goes — tomorrow's list, no debate, every time. A stretch goal fixes where effort has to go — toward a genuinely new strategy, because the old one is visibly insufficient, no debate, every time. Neither leaves the choice open in the moment it would be hardest to make well.

The principle underneath both

A decision made once, in advance, and applied automatically outperforms the same decision remade every time under pressure — whether the decision is "where does this new task go" or "do I keep doing what I've always done." Removing the in-the-moment choice is what makes both methods actually stick instead of collapsing back to habit the first hard day.

What that makes the real goal

Protect a committed course of action from being derailed by whatever shows up next, whether what shows up is a new task or the temptation to retreat to a familiar, comfortable method. The goal is a plan that survives contact with a normal, interrupting day.

Other practices that serve the same goal

Getting Things Done, David Allen's system, pursues the same protection through a different mechanism: a trusted external capture system for everything that lands on you, reviewed on a schedule rather than acted on the moment it arrives, which has decades of practitioner use behind it though the framework itself has been tested less rigorously than the psychology it draws on. Timeboxing — assigning a fixed block of calendar time to a task and stopping when the block ends regardless of completion — protects the plan from the opposite direction, capping how much any one task, however urgent it feels, is allowed to eat into everything after it. Both share the same objective as Do It Tomorrow: decide the boundary in advance, not in the moment the pressure is highest.

Using Do It Tomorrow to Contain a Stretch Goal

The moment you set a stretch goal, start a dedicated tomorrow list just for it, separate from your general one if the volume warrants it. Every idea the stretch goal throws off today — a person to call, an angle to test, a half-formed strategy — goes on that list instead of getting acted on immediately or, worse, running in the back of your mind all day. Tomorrow, you work that list in order, which forces you to actually rank the ideas rather than chasing whichever one felt most exciting when it arrived. A rep chasing a 40%-higher target who has this rule in place writes "try the referral angle with the Meridian account" on tomorrow's list at 2pm instead of dropping the client call she's on to go try it right then — and by the time she gets to it tomorrow, in order, she's often decided it wasn't actually the best idea on the list.

Using a Stretch Goal to Keep Do It Tomorrow From Going Stale

Do It Tomorrow has its own failure mode: because the list is closed and orderly, it's very good at helping you execute the same routine tasks smoothly forever, including routine tasks that have quietly stopped being the best use of your time. A stretch goal is the corrective. Once a quarter, set one target on your tomorrow-list work that your current routine, honestly assessed, cannot reach — not a bigger number on the same tasks, a number that requires different tasks. This forces new, unfamiliar items onto the list instead of only the comfortable recurring ones, so the system that's excellent at protecting today from chaos doesn't also protect today from ever changing.

Wednesday, Three Weeks Into the New Number

You committed to a stretch goal that means growing your client roster by a number your current referral-only approach has never come close to. It's Wednesday. You're two calls into the closed list you wrote last night when an email arrives suggesting a partnership with a competitor's overflow clients — genuinely promising, genuinely relevant to the stretch goal, and genuinely not what you planned to do in the next twenty minutes. The old habit is to drop everything and reply immediately, because it feels connected to the big goal and therefore urgent. Instead you write one line — "draft reply to Kessler re: overflow partnership" — on tomorrow's list, and finish the call you're on. Tomorrow it's the second item on a four-item list, not a fire interrupting a day that had four other things in it, and you notice by the time you get to it you've had a night to think about the terms you actually want.

When this is worth reaching for

You have set an ambitious target AND you notice the target itself is generating a stream of new, tempting, half-formed tasks that threaten to eat the day you're currently in. If your stretch goal is a single big project rather than an ongoing source of new tasks — training for a race at a pace you've never hit, say — there's less for the closed-list rule to catch, because the goal isn't generating a stream of new interrupting to-dos day to day.

Where this does not apply

If your goals are modest and stable — hit the number you hit last quarter again — Do It Tomorrow is still useful on its own, but there's no stretch goal here to protect against, so pairing them adds a step with nothing for it to do. And if you're in a role where genuine same-day response is the job itself — emergency dispatch, live customer support during an outage — deferring every new item to tomorrow isn't discipline, it's malpractice; the closed-list rule assumes most of what lands on you can honestly wait a day, and in some jobs that assumption is false.

What the evidence does and does not support

The goal-difficulty research behind stretch goals is genuinely strong — decades of studies on specific, difficult goals producing more effort and performance than vague or easy ones — but the same body of research is equally clear that beyond a certain difficulty, variance rises sharply: more spectacular wins and more outright failures, not a smooth improvement. Do It Tomorrow's specific closed-list mechanic has not been tested in controlled studies; the practitioner evidence for it is extensive but observational, and the general principle it leans on, pre-committing to a response in advance, does have randomized support from other contexts. Nobody has run a study on capping a stretch goal's overflow with a closed-list method specifically — the two literatures have simply never met, so what's written here about how they interact is mechanism, not measurement.
