Billy, you don't have to be perfect to be a hero. Being a hero is about helping others and having courage. Including the courage to get back up again and try after you stumble and fall.

[She might not consider herself much of a hero, but she's grown up surrounded by people who have contributed toward saving the world. Not a single one of them is perfect and she admires them all anyway.]

And if that means your friends have to offer you a helping hand so you can get back up, that's not something to be ashamed of. It means that people like you enough to want to be there.
