Being a parent is the hardest thing in the world... the psychological toll it takes on you because these lives are in your hands. I take it very seriously.

For me, getting comfortable with being famous was hard - that whole side of it, the loss of anonymity, the loss of privacy. Giving up that part of your life and not having control of it.

You know, when I am working, I take really, really good care of myself. I eat really well, and I exercise, and again, I have this team of people pulling me together every day.

When I go to work and when I'm in the public eye, I take much better care of myself. Because when I'm not working, I do indulge more.

There are certain scenes you do in a movie that are like catching a wave, and you leave work feeling elated - almost as though you've purged something. That's rare, but you do live for those moments.

Where I came from, the idea of going into show business was just ridiculous; in fact I didn't tell anybody because I knew people would laugh at me. So I sort of snuck around and got some pictures and got a resume together and, of course, lied and said I did all kinds of things I didn't do.

I don't know if it's naivete or just narcissism, but I start out with this notion that I can do anything. It's not until I get into it that I realize what I've thrown myself into, and then I will do anything not to humiliate myself. And that, I think, is the secret to my success.
