With age, you see people fail more. You see yourself fail more. How do you keep that fearlessness of a kid? You keep going. Luckily, I'm not afraid to make a fool of myself.

Acting is something I love. It's a great craft that I have a lot of respect for. But I don't think it's any greater challenge than teaching 8-year-olds or any other career. In my life, I try not to make it more important than it is and I just hope that rubs off on the people around me.

Becoming a father, I think it inevitably changes your perspective of life. I don't get nearly enough sleep. And the simplest things in life are completely satisfying. I find you don't have to do as much, like you don't go on as many outings.

I've always felt that if you back down from a fear, the ghost of that fear never goes away. It diminishes people. So I've always said 'yes' to the thing I'm most scared about. The fear of letting myself down - of saying 'no' to something that I was afraid of and then sitting in my room later going, 'I wish I'd had the guts to say this or that' - that galvanizes me more than anything.

I think the most interesting question is, why do you act? I act because I have felt in acting some of the most free moments of my life...I think it's also one thing that scares me the most.

I have a terrific marriage, but unlike a lot of relationships where they ebb and flow, no matter what happens you fall deeper and deeper in love every day. It's kind of the best thing that can happen to you. It's thrilling.
