Don't sleep as much as you'd like. Talk slow, think fast. Call your parents. Life is not a movie so don't even try to rewind to the good parts. Even if you're on the right track, you'll get run over if you just sit there.
Silence is sometimes the best answer.
Forget the things you give, but remember the things you take. I wonder why I wasn't born with my foot in my mouth since that is where it seems to be the most comfortable. Character is doing the right thing when no one is looking. Believe and trust in people, but lock your car doors. Experience is what you get when you don't get what you want.
