The Willpower Instinct
Kelly McGonigal
- Habits
- Psychology
A book based on “The Science of Willpower”, the course Kelly McGonigal teaches at Stanford. She divides self-control into three powers — “I will”, “I won’t” and “I want” — and uses research to explain why we lapse and procrastinate and how to fix it.
Key ideas
- Willpower is like a muscle: it tires by evening, but it can be trained.
- Sleep, movement and calm breathing give more self-control than forcing yourself.
- Praising yourself for “good” behavior gives you moral license to lapse — keep your eye on the goal, not on your merits.
- Guilt after a lapse leads to another lapse, while self-compassion leads back to the goal.
