Judy Greer

I remember my choir teacher in high school told me, 'When in doubt, sing loud.' I'm a terrible singer, but I always auditioned for the musicals, and would get cast in them because I really would just put it all out there. That was really good advice, and I think it works for everything, not just acting.

The truth is, if I was maybe better or funnier or prettier, wouldn't I have starred in a movie? I can see it objectively as a businesswoman - if no one's buying your product, then there's not a desire for it.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.
