30. Be Happy
The most important advice I could have given myself was to be happy — no matter what. No matter what the outside circumstances of life were, be happy. I would tell myself that basing my joy on the things that happened (or didn't happen) or the things I had (or didn't have) meant putting conditions on my happiness. And doing that is a recipe for being miserable. So enough with the worry and the want and the shame — just be happy.
