In 2009, researchers uncovered a truth most people still ignore: Willpower works like a muscle. Use it all day, and it burns out. Every decision you make—what to eat, what to wear, what email to answer—slowly drains your mental battery. By night, you’re running on fumes. That’s why cravings hit harder. Why discipline disappears. Why the important work suddenly feels impossible. Here’s the part the world’s top performers already understand: They protect their decision-making energy. Why do some CEOs wear the same outfit every day? Why do elite athletes follow identical warmups? Why do high-level entrepreneurs create strict routines? Because they’re not trying to be interesting. They’re trying to stay effective. They refuse to waste willpower on low-stakes choices when they need that energy for the ones that actually change their life. Meanwhile, most people burn their prime mental strength on nonsense— scrolling notifications, debating breakfast, flipping through outfits— and then wonder why they don’t have the bandwidth to build wealth, scale a business, or lead with clarity. Here’s the truth: Your energy is your leverage. Stop spending it on cheap decisions. Save it for the choices that print money, move mountains, and build your future. High performance isn’t about doing more. It’s about wasting less. 🚀
