Do 2-minute 'tiny habits' actually lead anywhere or is it self-help fluff?

It scales, but only if you understand what the two minutes are FOR — and the book's critics and fans both routinely miss it. What tiny habits actually train: showing up on cue. The automation you're building is the cue→action link ('after brushing, I exercise'), and that link doesn't care whether the action lasted 2 minutes or 40 — it cares that the sequence fired. Most habit failures are failures to START (the negotiation at the couch), not failures of capacity. Two minutes wins the negotiation by making refusal absurd: you cannot talk yourself out of one pushup with a straight face. Why it beats going big: the person doing 45-minute workouts on motivation quits in week 3 with an all-or-nothing identity crisis. The one-pushup person has no crisis available — and in practice, once you're on the floor in workout clothes, one pushup becomes eight becomes a routine. Starting is the activation energy; the rest is downhill. Where it legitimately fails (your homeopathy instinct isn't baseless): - If you stay ceremonially tiny forever ON PURPOSE. The 2 minutes is a gateway, not the destination — scale when showing up is boringly automatic (usually 3–6 weeks). - Goals needing threshold doses (marathon training, exam prep on a deadline) — tiny habits build the identity and the slot in your day, but eventually the volume has to arrive. Use it for: anything you've failed to start three times. Skip it for: things you already do reliably. It's a starter motor — fluff only if you never engage the engine.
