(Why "habit changes fate"? Because 40% to 50% of a person's behavior depends on unconscious habits.Habit formation requires four steps: prompt → desire → response → reward. Cues trigger cravings, cravings trigger responses, and responses provide rewards that satisfy cravings and are ultimately associated with cues. These four steps together form a neural feedback cycle - prompt, desire, response and reward; Tips, desires, reactions, rewards - eventually you develop a natural habit and complete the habit cycle.According to the four steps of habit formation, James Claire, a famous habit research expert and founder of habit college, summed up the corresponding four laws of habit formation: make it obvious; Make it attractive; Make it simple and easy; Make it pleasant. Through these four rules and 56 specific cases, this book helps you quickly develop good habits. At the same time, using these four opposite rules can help you get rid of bad habits.)
