Something happens to people around fame and power and money - it can bring out the worst and best in people; it's a monster you have to tame.

I'm not doing this to be a pop star. I've had plenty of money and attention. I'm doing it for credibility.

It's hard for me to be happy because I'm always worried about something going awry or what could happen to screw it up. It's hard for me to sit and look around, going, 'Ah, I'm really happy.' I'm not that kind of person.

I always think that struggle can bring out the best in people - or the worst.
