Habit Architect

Most habits die by week three — not from weak willpower, but from fighting your own brain with a strategy built for people who never slip. This playbook uses the actual science of habit formation (the famous 66-day average) to build one keystone habit that unlocks bigger change. It covers picking the right keystone habit, implementation intentions and habit stacking, the 2-minute floor, a 66-day build with three phases, daily check-ins, weekly reviews, and a never-miss-twice recovery rule — all as copy-paste prompts your Personal Growth Ally can run.
