Here are some things I try to live by:
1. try to live a 'good' life and choose 'good' people as friends.
2. find out your strengths and interests and go for it, work hard with a career in mind. There is absolutely nothing wrong with higher ed, or professional sports or [fill in blank].
3. don't worry too much about the existence of God/afterlife, etc. no one knows about this for sure.
I'll get off my soap-box now.
