To me, songs come of their own volition - and with an open-ended philosophy.

I made the decision to take on board the critical feedback. Reviews are something you can easily ignore as a performer or writer but I chose to not ignore them here and I think that I benefited. I think I'm stronger for it - and I have a tougher skin as a result.

I think I've done a pretty fantastic job, but of course I want to sell millions of records.

I've had my ups and downs, and I definitely have a sense - in America, especially - that once you've made your mark and gotten your Rolling Stone piece and your Grammy nomination, that they're on to the next piece of meat, and they don't necessarily like to follow the twists and turns of an artistic career.

My creative process involves that old saying: It's 90% perspiration and only 10% inspiration.

I can't believe this is happening to me. The weirdest thing is it was just a dream, and now it's actually real. It's hard to believe sometimes.

One of my greatest times of inspiration is when I'm traveling or living in a new country - there's a tremendous freedom that comes from being unfettered by your own, familiar culture, and by seeing the world from a different point of view.

That's a part that's always a challenge for athletes: trying to keep the passion alive while knowing it's still your job. There's no question that at some point, probably sooner rather than later, I'll be pretty burned out. And when that time comes, then I'll take a step back and take a look at it and see if I want to keep going.
