There is a big difference between what I do onstage and what I do in my private life. I don't put my living room on magazine pages.

Medicine comes with hope: the hope of having a healthy child, the hope of being able to raise your family.

I'm very intrigued that in this culture of reality television and celebrity - which is an enormous industry and generates billions and billions of dollars - we're so resourceful.

I haven't lived my life through my daughters. Some parents devote everything to their children, which must be so hard, and it's very beautiful. But I'm a working parent, so I've always kept my own life.

I have a calling in my soul, if you like, to try to make my life in some way worthwhile. What is the value of my existence?

At times, I've been so absolutely terrified of what I was about to do, whether it was public speaking or performance. Whatever it was, sometimes it had me really, really shaking in my shoes, and I decided that I was going to do it no matter what. And, of course, the critic is there, and afterwards, there's this, "Was it good enough? Was it really all I wanted to say?"

More than anything, I think everything about appearance is illusory. People see you, and they think they understand what you're projecting, but actually, they have their own interpretation of it, or they put a label on you.
