Let the micro start pull you into more

Often you do more than the minimum once you have started — but the minimum is the only requirement.

Why it works

The hardest part of a behavior is starting; once in motion, continuing is far cheaper. A micro habit lowers the start cost to near zero, and frequently the momentum carries you past the minimum on its own. The key is that the extra is a bonus, never the requirement — keeping the bar at the minimum is what preserves the guarantee that protects the streak.

How to do it

1. Commit only to the micro version; allow yourself to stop the instant it is done.
2. If momentum carries you further, accept the bonus without raising tomorrow’s requirement.
3. On low days, do exactly the minimum and count it as a complete success.

Evidence

Aligns with research on activation energy (starting is the bottleneck) and with task-initiation effects where beginning a task increases the likelihood of continuing. The "minimum stays the rule" framing is practitioner advice. Wood & Rünger (2016) explain how, once a cue sets a behavior in motion, continued action runs on habit rather than renewed deliberate effort. (mechanistic)

Relying on momentum to always do more is a trap; if the bonus quietly becomes the expectation, the habit loses its bad-day insurance.

Common mistake

Letting the frequent "extra" silently become the new minimum, so the habit stops being micro and collapses the first time you cannot do the bigger version.
