Willpower by Roy F. Baumeister & John Tierney — book cover

Willpower

Roy F. Baumeister & John Tierney · 2011

Willpower isn't a fixed character trait you're either born with or not. It's a real, measurable energy that fuels every act of self-control. This book shows how it gets depleted, how to refuel it, and how to train it like a muscle so it carries you toward the life you want.

Why it’s on the shelf

Landmark research on self-control as a trainable, depletable resource you can strengthen.

Two of the ideas you’ll keep

The Clif summary of Willpower pulls out 7 insights. Here are the first two.

  1. Treat willpower as one shared fuel tank. Resisting dessert, biting your tongue in a meeting, and grinding through a hard report all draw from the same reserve. Stop stacking your toughest self-control demands into the same window.
  2. Refuel the tank with glucose and sleep. Self-control nosedives when your blood sugar is low or you're exhausted. Before a high-stakes decision, eat something with slow-release energy and never negotiate hard on an empty stomach or no sleep.
