I agree with Yenta. I've become sort of the Dear Abby of my circle of friends, and it's because I've kind of "been there, done that". Wisdom comes from experience, not being lucky enough to have perfect relationships.
"You can only become truly accomplished at something you love. Don't make money your goal. Instead, pursue the things you love doing, and do them so well that people can't take their eyes off you."
