Take care of yourself: When you don't sleep, eat crap, don't exercise, and are living off adrenaline for too long, your performance suffers. Your decisions suffer. Your company suffers. Love those close to you: Failure of your company is not failure in life. Failure in your relationship is.

The things that keep nagging at you are the ones worth exploring.
