I love what I do. And why not be nice? I mean, I've seen people who work and they're apparently not enjoying it, and they're making sure everybody knows it.

The truth is I'm a dork. I collected comics. I still love cartoons. I'd rather be at home on a Friday night than out at some club… My sense of humor is that of a geek. My likes and dislikes are that of a geek. I've memorized every crappy sci-fi movie there is, but still haven't seen Schindler's List.

I enjoy the art, and I enjoy drawing. I think my printing to this day looks like the printing right out of a comic book.

It's hard to shake a stick at success.

Whatever our bedtime was as kids, we could stay up an extra half hour if we were reading. My parents didn't care as long as I was under the spell of a Stephen King or a Douglas Adams. Now I read in bed. I read at work. I read standing in line. It's like, 'Hello, my name is Nathan and I am a reader.'

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.

Do something today you've been afraid to do. A decision based on fear is the wrong decision.
