Tiny Habits by BJ Fogg, an honest summary
Tiny Habits (2020) argues that behaviour happens when motivation, ability and a prompt converge, and since motivation is unreliable, design for ability: shrink the habit to something near-effortless (floss one tooth, two push-ups), anchor it after an existing routine, and celebrate instantly to wire it in. Fogg ran the Stanford Behavior Design Lab and taught many of the field's popularisers.

The ideas that hold up
- Designing for low motivation is exactly right for procrastination: plans that require feeling like it fail on the days that matter, and tiny entry points do not.
- Anchoring a new behaviour to an existing routine is a form of implementation intention, one of the best-evidenced techniques in behaviour change.
- Shrinking the task attacks the start-up aversion directly; it is the same mechanism as the two-minute rule, and starting reliably predicts continuing.
- Troubleshooting failures as design flaws rather than character flaws removes the shame spiral that keeps many procrastinators stuck.
Take with a pinch of salt
- The instant-celebration step is the model's most original and least evidenced claim; the emotion-wires-habits mechanism is plausible but not demonstrated at the level of Fogg's confidence, and many readers find deliberate celebration unnatural.
- B=MAP is presented as settled science; it is a useful heuristic from design practice more than a validated psychological law.
- Tiny habits build routines well but scale awkwardly to big one-off projects; a thesis is not a habit, and the book says less about that case.
Grounded in Fogg's lab and consulting work rather than published trials of the method itself; its anchoring component borrows the strength of the implementation-intentions literature.

Frequently asked questions
Tiny Habits or Atomic Habits?
They share DNA; Clear credits Fogg's ideas and both use anchoring and shrinking. Atomic Habits is broader and better written; Tiny Habits is more precise about the mechanics of one habit at a time and more forgiving in tone. For pure getting-started problems, Fogg's version is the sharper tool.
