You may be surprised just how much small daily decisions impact the willpower you have for important choices. And most importantly, it turns out there are simple choices you can make that will help you master your willpower and make better decisions on a more consistent basis.
As it turns out, your willpower is like a muscle. And similar to the muscles in your body, willpower can get fatigued when you use it over and over again. Every time you make a decision, it’s like doing another rep in the gym. And similar to how your muscles get tired at the end of a workout, the strength of your willpower fades as you make more decisions.
Researchers often refer to this phenomenon as decision fatigue. When the judge on a parole board experiences decision fatigue, they deny more parole requests.
This makes sense. When your willpower is fading and your brain is tired of making decisions, it’s easier just to say no and keep everyone locked up than it is to debate whether or not someone is trustworthy enough to leave prison. At the beginning of the day, a judge will give each case a fair shot.
