Regular exercise. I used to have an idea that successful people had their life under control to a degree that they could find time to exercise 3-4 times per week. After I started running regularly and saw the change in myself, I've come to think successful people are successful in part _because_ of their exercise, not the other way around. It gives a lift to everything you do. It motivates you to be the best version of yourself you can be, starting a virtuous loop of eating better, continued education, big picture thinking and other self-improvement.
