Based on a fundamental truth: habits are not created—they are built through successive cycles through the Hook. ## Core Principle **The Hook Model** = a four-phase process that connects the user's problem to your solution frequently enough to form a habit. ``` Trigger → Action → Variable Reward → Investment ↑ │ └──────────────────────────────────────┘ ``` **Habit Zone:** Products enter the "habit zone" when used frequently enough and with enough perceived value. The goal is to move users from deliberate usage to automatic, habitual behavior. ## Scoring **Goal: 10/10.** When reviewing or creating product engagement mechanics, rate them 0-10 based on adherence to the principles below. A 10/10 means full alignment with all guidelines; lower scores indicate gaps to address. Always provide the current score and specific improvements needed to reach 10/10. ## The Four Phases ### 1. Trigger **Core concept:** The actuator of behavior. What prompts the user to take action? Triggers come in two forms: external (environment-driven) and internal (emotion-driven).
