I do think - I always tell that to young people - go to college, do theater, work with an audience. Don't try to learn how to act in front of millions and millions of people. Don't make that your first ambition, to be on a sitcom or get into the movies. Learn who you are as an actor, and the best way to do that is to do it in front of an audience.
I grew up with this crazy upbringing of living many places and always being the new kid in town, not like a service brat where you're always going to school with other new kids in town. I was constantly arriving in small towns and going to school with kids who'd been together since they were in kindergarten.
