#2186 Willpower by Roy Baumeister and John Tierney

Self-control isn’t fixed—it’s a skill you can build.

Today’s book: Willpower by Roy Baumeister and John Tierney—a science-backed guide to understanding what drains your willpower, how to strengthen it, and why it’s the key to long-term success.

Here’s your 1-minute summary:

  • Willpower is like a muscle. It gets fatigued with overuse—but stronger with practice and rest.
  • Decision fatigue is real. Every choice costs mental energy. Simplify routines and automate the trivial.
  • Track your behavior. Self-awareness is the foundation of self-control—what you monitor, you improve.
  • Use it on what matters. Willpower is limited. Spend it on your top priorities, not on resisting donuts or inbox pings.
  • Rest and fuel wisely. Sleep and stable blood sugar keep your willpower tank full. Don’t try to power through on empty.

Your greatest power is self-mastery. What’s one way you’ll train your willpower today?

As always, check out the Notes for more. We've got Willpower 101, Habits 101, and Algorithms 101. I'm kind of a fan of using your willpower wisely to install habits that run on autopilot so you can show up as the best version of yourself.
