Habit Phase

Not all habits are in the same place at the same time. A new habit that requires conscious effort every day is in a completely different state than a habit you've done for three years without thinking. Recognizing where a habit is in its lifecycle — its phase — allows you to apply the right support at the right moment.

Most models describe four phases. The Intention phase covers the first days, when motivation is high but the habit hasn't been tested by real life. The Resistance phase — roughly days 8 to 21 — is where most people quit, as novelty fades, schedules push back, and the habit feels like work. The Rhythm phase follows, when the habit is becoming predictable but still requires conscious reinforcement. The Automatic phase is the goal: the habit fires without deliberate effort.

Each phase requires different tactics. In Intention, the priority is designing a good cue and keeping the routine so small it's impossible to skip. In Resistance, the priority is friction reduction and consistency over quality. In Rhythm, the focus shifts to raising the baseline. In Automatic, the priority is protecting the habit from disruption events.

Decade tracks each of your habits against its current phase, surfacing contextual guidance that matches where you actually are rather than offering generic advice. A Resistance-phase habit needs different support than an Automatic-phase habit maintained over years.
