• The habit loop consists of:
  • Cue: Trigger for the habit (e.g., alarm clock).
  • Routine: Set of actions (e.g., making coffee).
  • Reward: Enjoyment from the habit's completion (e.g., drinking coffee).
• Habits account for about 40% of daily decisions, often made unconsciously.

Chapter 2: The Golden Rule of Habit Change

• Bad habits are often driven by the craving for a reward at the habit loop's end.
• To change a habit, alter the routine while keeping the cue and reward constant.
• Example: Rey replaces drinking whiskey with swimming to relieve stress.
