Define What “Done” Means Before You Start (an ADHD Must)

Unfinished tasks often have no finish line. Here’s how defining “done” upfront helps ADHD brains start, stay on track and actually stop.

The short version

  • Many tasks never finish because “done” was never defined.
  • A clear finish line reduces perfectionism, scope creep and endless polishing.
  • Write one sentence: “This is done when…” before you begin.

“Clean the house.” “Work on the presentation.” “Organize the closet.” Notice what these have in common? None of them has a finish line. With ADHD, a task without a finish line tends to either never start or never stop.

Why “done” matters for ADHD

  • Starting: a clear end makes the task feel smaller and safer to begin.
  • Staying on track: you can check whether a side quest helps you reach “done.”
  • Stopping: without a finish line, hyperfocus and perfectionism keep going long after the useful part.
  • Feeling good: finishing gives you a real sense of completion, which builds momentum.

The one-sentence method

Before you start, finish this sentence:

This is done when…

Make it specific and observable:

VagueDone when…
Clean the kitchenCounters are clear, dishes are in the dishwasher and it’s running
Work on the presentationSlides 1–5 have titles and one sentence each
Organize the closetThree bags of donations are in the car
Study for the examI’ve done 20 practice questions and checked the answers

Good-enough versions

For tasks that tend to spiral, add a good-enough version:

  • Minimum: the smallest version that counts
  • Good: what you’ll aim for today
  • Extra: only if time and energy allow

This is especially helpful for perfectionism and on low-energy days.

Make it visible

Write “done when” at the top of the document, on a sticky note, or as the name of the task in your list. When you finish, tick it off on purpose. Notice it. That moment matters more than it looks.
