Tasks
Define “done” before you start, or you will never finish
Updated August 2026 · 4 min read
Short version
- Without a definition of done, every task becomes open-ended polishing.
- A pre-agreed finish line closes the loop and stops the perfectionist stall.
- Done can be small, ugly, and still count — if you named it in advance.
The finish line that keeps moving
You sit down to tidy the room and three hours later you are reorganizing a drawer nobody opens. The task never ended, because it never had an edge.
For many ADHD brains, “better” is endless and “done” is undefined. Interest keeps finding one more improvement, and stopping feels arbitrary — even a little wrong.
Perfectionism is often just interest in disguise. The task stays shiny as long as it stays unfinished.
Why undefined done stalls you
An open-ended task is hard to start, because your brain cannot see the whole shape of it. It is also hard to stop, because there is always visible room to improve.
- Starting feels risky — how long will this take? Nobody knows.
- Stopping feels like quitting — there is always one more tweak.
- Finishing brings no reward — the loop never actually closes.
Undefined done is why so many projects stall at ninety percent. The last stretch holds no novelty, and the end was never real enough to aim at.
Write the finish line first
Before you begin, complete one sentence: “This is done when ___.” Make it observable, not a feeling.
- “Done when the surfaces are clear” — not “when the room feels nice.”
- “Done when the email says the three things” — not “when it reads well.”
- “Done when twenty minutes are up” — a time box counts as a definition too.
- “Done when the first draft exists” — editing is a separate task with its own done.
Small and ugly counts if you named it in advance. You can always choose to continue — but that becomes a new task with its own done, not an endless first one.
Hold yourself to the old definition
Midway through, your brain will move the goalposts. “While I am here, I might as well…” is the perfectionist stall putting on a helpful voice.
When the definition is met, stop on purpose and let it be finished. A closed loop is fuel for the next start — and a brain that watches loops close starts to believe starting is worth it. Finishing on a definition you chose is a skill, and it compounds.
