Playing Sheldon is just heaven for me. I realize how enormously lucky I am to play a role that makes me so incredibly happy. As I told Chuck Lorre in a Christmas card a few years ago, I'm living a version of the dream.

I was very fascinated with meteorology at a young age. I lived on the Gulf Coast and hurricanes blew through there. That is the class I failed in college: meteorology.

I had a very strong interest in music, specifically the piano from a very small age.

There's no audience to wonderfully get in your way when you're doing a single-camera anything, whether it's a sitcom or drama or film. And I do mean that in the best way.

Every time I think about writing, comedy doesn't interest me in the slightest. I can play comedy, but I don't think in terms of comic dialogue.

I didn't have an imaginary childhood friend, but I did one day imagine somehow tiny green men, and they were only tiny and green because my brother had a ton of toy soldier toys that came on a skateboard plank type of thing, and I just envisioned in this car driving to church with my mom, they were there.

My choices in projects have all been character or role-based, and on a financial level, it's obvious: as an actor on a TV series, I get a wonderful paycheck, and a consistent paycheck, which doesn't always happen when you're doing theater or movies.
