I always knew I'd be in music in some sort of capacity. I didn't know if I'd be successful at it, but I knew I'd be doing something in it. Maybe get a job in a record store. Maybe even play in a band. I never got into this to be a star.
Everybody uses mime and gesture in real life, though we don't realize it. It's very useful as a performance technique, though it can be boring to watch on its own.
