I don't believe in mistakes. Never have. I believe that there are a multitiude of paths before us and it's just a matter of which way we walk home. I don't believe in regret. If you regret things about your life, then I'll bet that you're not paying attention. Regret is just imagining that you know what would have happened . But you don't know; you can't possibly know. Spend a little time thinking about that - but not much. You could drive yourself crazy thinking that way.
