Hands‑On Usage Scenario

• Morning coffee habit:
  • Cue: Alarm clock rings.
  • Craving: Desire for warmth & alertness.
  • Response: Brew coffee.
  • Reward: Taste and energy boost.

Diagnostic Application

If a habit stalls, tweak the loop:

• Make cue more obvious, craving more attractive, response easier, or reward more satisfying.

Origins

Extended from Charles Duhigg’s cue‑routine‑reward model; Clear adds “craving” to capture motivational drive.
