One thing I've learned is I actually don't like variety very much. I like having the same thing over and over: assorted lean proteins, arugula salad, quinoa or brown rice with soy sauce, olive oil, lemon, and salt. Those ingredients can pretty much get me through the week.
Acting is the most bizarre profession. You can stay in it for years and not really be in it and be waiting for someone to give you an opportunity. It's like when I watch 'American Idol' and see people who have been told to believe in themselves at all costs: It's not always a good idea.
I'm baffled when young actors aren't familiar with current film, television and theater, or aren't interested in older films or plays and the history of the craft in general. If you don't know what's out there, and what came before, then how can you picture yourself working, and how can anyone else?
