My inspirations include the Beatles - love, love, love them - Elton John, Carole King, and Stevie Wonder.

We kiss and hug our kids a lot! And even now when our son lives 3,000 miles away, we talk every day, sometimes several times.

I think we should all live the moment. But you also have to think ahead. You have to think, 'Am I going to be happy with this five, ten years from now? Is it going to let me evolve and grow, or am I going to grow to one day wish I had never done it?' Sometimes you just have to think a little bit ahead.

My son traveled the world with me on every tour. He wasn't a lover of school, so it was easy with him. I had a tutor on the road, keep him at the same level, so when he'd pop back home he'd go right back in.

The challenge is always as a writer, is this going to work, because it's a very intimate process, and I tend to be very introverted and insular, and when I write, it's in my head.

There's no reason that just because you're a celebrity you can't write.

There are so many difficult things we're living through in the world today, so many horrible events, but we cannot let them stop us. No matter what happens, I feel you must move forward with optimism and not get totally sideswiped.
