This is an important lesson, learn from other people's mistakes. The things I will absolutely not screw up again, ever, are the things I really, really suffered from. But then I could apply this to seeing how other people destroyed their lives, and use the pain I already have to protect me from those mistakes too. Was it Ben Franklin that said "experience is the worst way to learn"? (I think it's in reference to making bad decisions)
