The problem

You have started this habit before

Habits rarely fail because people are lazy. They fail in week three, quietly, when motivation has gone and nothing was built to catch the fall.

The tracker deliberately holds one habit, not five. Ninety days is long enough for it to stop requiring a decision.

Why ninety days

Long enough to stop being a decision

The popular "21 days" figure is a myth. Research puts the average closer to two to three months, and it varies by person and habit — which is exactly why the tracker runs to ninety and reviews at thirty.

One habit

Defined precisely enough that you cannot argue with it at 7am.

The chain

One mark a day. The visible streak does the persuading.

Three reviews

Day 30, 60 and 90 — adjust rather than abandon.
