The habit loop: why naming the cue and reward changes everything
A habit is a three-part loop — cue, routine, reward — your brain runs on autopilot. Naming each part is the cheapest, fastest way to make a habit easier to keep.

A habit is a three-part loop: a cue that triggers the behaviour, a routine you actually do, and a reward your brain remembers. Charles Duhigg popularised this model in The Power of Habit; behavioural-design researchers like BJ Fogg and Wendy Wood have spent decades refining it.
Most people skip naming the cue and reward. They write down "exercise daily" and wonder why discipline keeps failing. Naming each part of the loop costs nothing and tells your brain what to attend to:
- Cue. A time, a place, an emotion, or a preceding action. "After morning coffee" is a stronger cue than "in the morning" — it's tied to a concrete event.
- Routine. One specific behaviour. "Twenty push-ups" beats "exercise" because there's no decision left to make.
- Reward. What you feel when it's done. Not a treat — the internal satisfaction. "Energised", "proud", "calmer".
When you fill out the loop in HabitForge, it's not paperwork. It's the most useful sentence you'll write about that habit. Read it the moment the cue fires.
Why missing a day costs less than building one
The strength curve in HabitForge is asymmetric on purpose. Completing a habit adds a small amount of strength; missing it removes a slightly larger amount — but it never resets you to zero. You're not "starting over". One missed day is data, not failure.
What actually breaks a habit is the second missed day in a row. Skip once, recover the next day. That's the single most useful rule from habit research, and it's why HabitForge celebrates recovery as much as streaks.
