“The key to being a minimalist is making a routine out of just about everything that is not core to your mission. When decisions are automatic, you skip the conscious deliberation and associated brain activity. You move straight from encountering a situation (e.g., I need to get dressed) to performing an action (e.g., putting on the same shirt as I do every day) without expending energy in between. In a sense, you are cheating fatigue, saving your mental muscle for things that actually matter to you. The more decisions you make automatic, the more energy you’ll have for the work you deem important.”
