Exercise - I try to lift, run, or some combination of the two at least three times a week. It really helps to clear my mind, especially after a stressful project. Read/Write - It took me longer than it should have to realize how critical the ability to write well is. Games - Chess, poker. These are more just hobbies for fun, but I think both rely on some really useful principles in life, such as the importance of a plan, decision making with limited information, etc.
