I can't justify taking one minute of free time for myself. I'm restless to do things. Anything! Hell, I'll watch Top Chef and I think, "God, maybe I could be a chef," I'll watch a dancing show and think, "God, maybe I can be a dancer." I mean, that's how I got into acting. I visited an improv show and thought, "Hey! I could do this." It sounds like arrogance, but I don't think it is... just an ambition to reach out and touch something new.

The most fun thing about doing the show is that, as a nerd, the fun has been in learning and having it be like a grad school for me, every day. Every moment is a new experience. Every conversation is a new gain.

I felt like I've needed to ask my parents up until about four years ago about everything. They have helped me tremendously, I came out of college with no debt. Everything they made, they just poured into my education.

I try not to question the choices of the production. They've done such a good job up until now that I'm sure they have the right plan in place. And to be quite honest, we don't even know exactly when it will be coming out.

I like documentaries because there's nothing to nitpick or criticize about scenes if they aren't just right. It's about honesty and real-life circumstances coming out. Granted it can be swayed by how people tell that story, but overall, I like it because it is true.

Confidence. That's huge as an actor. Confidence can get you a long way. Maybe it's a cultural thing, being Korean, but my first reflex has always been to exude humility - but it doesn't help you in acting. For acting, humility isn't the best thing. It'll weaken your work. So it's a head game for me. "Can I really be confident in knowing my skill set is down? Can I perform like I own this role?"

The book is about zombies, in that it is the over-arching theme, but what's going on is the story of these people and how these survivors deal. I think that's so much more of an interesting story, and that's what really gets and hooks these readers into the book and the show. It's a mix of fans of drama, fans of AMC, fans of horror and fans of Frank [Darabont]. It's a lot of people just coming together and realizing a genre doesn't have to be fixed in one specific detail.
