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.

Because I believe actually the more you do something, the less frightening it becomes because you start to realize the outcome is not as important as you think.

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.
