Nutrition, mind-set, productivity, performance, fitness, sex, sleep—when we look through a keyhole at these areas of focus, we forget that they are interconnected and interdependent. They are spokes on the wheel of the day, every one of them necessary to ride the twenty-four-hour cycle into a life worth living. Because a day isn’t just about what you put into your body, how you look in the mirror, or how much production you can squeeze from eight hours of work. It’s about how you feel, whose lives you connect with, and how much fun you have along the way.
