I'm fortunate enough that every job I do seems to be, at the very least, teaching me something fantastic. I make new friends. I work with talented people. And each project and experience seems to be better than the last. I seem to be topping myself all the time. I think to myself: "It can't get better, it can't get better..." And then something happens that makes me feel like I'm truly richer for the experience.

The trick is, when you grow up, find work that feels like play.

I thought what would be really just choice for a revamp and a reboot is 'The Greatest American Hero.' I think I'd be just that kind of perfect not prepared for this kind of thing, but thrust into circumstances he's not prepared for... that's another niche of mine. Unpreparedness. Not knowing what to do. I'm good at being that guy.

Basically, after an ABC sitcom I did, I ended up with a holding deal with 20th Century Fox. Absolutely cool. It pays you to be unemployed. And the bigger the entity that gives you the deal, the better.

I'm the biggest geek of all. Adventure, fantasy, comic books - I can't get enough.

I want my job to include a little adventure, a little more of a heightened reality than what I'm actually living. And 'Castle' has that. He gets this opportunity to tail these homicide detectives, and he's driven by that. He's a little immature, but he's obviously loving life.

I think about my own daily choices every day in terms of how to find happiness.
