What we've had to do is learn to control success, put it in perspective, and not lose the essence of what we're doing - the music.

I've never gotten thick skin. If you close yourself off and you get this protective armor, there is a price you pay with that - of not feeling. And feeling is important when you are a songwriter.

It's about you putting in the work, practicing every day, and hopefully one day you write the song the whole world wants to get down to. And one day you're going to be sitting next to Ellen DeGeneres talking about how you broke records and rocked the Super Bowl!

For some people, fame kills it and becomes more important than the music or the performance. But for me fame is like rocket fuel. The more my fans like what I'm doing, the more I want to give back to them. And my passion is so strong I can't sleep - I haven't slept for three days.

You have to be a bastard to make it, and that's a fact. And the Beatles are the biggest bastards on earth.

I'm quite happy with the music carrying on. I've never been one to clamor for fame. It just got dumped in my lap. The ambition is definitely not fame. The ambition is to be creative.
