I coined one of my favorite personal mantras, “Tomorrow Starts Tonight,” because before I go to bed I lay out my clothes, pack my day bag, set up my coffee pot, and even write a to-do list and schedule. Every micro-decision that I can make for myself ahead of time leaves me more willpower to dedicate to training the next morning, or to whatever big task is on my plate. If you’re planning your day on the fly, there’s no way it’ll be as efficient.
