It's hard not to get a big head in the film industry, there are people on a set paid to cater to your every need, from the minute you arrive until you go home. It's kind of strange, but not unpleasant.
I'm a big believer in therapy. I'm in therapy in real life. I think anytime you can bitch and moan about your own life to someone who really doesn't care that much, and can give you an objective opinion about what you're going through, I think that's valuable.
