Nothing is as important as passion. No matter what you want to do with your life, be passionate.
I do all kinds of roles - nerd, psycho, nerd, psycho, nerd, psycho - and occasionally someone kind of normal. It's weird, when I lived in Austin I was always cast as pretty normal people. But when I moved to Los Angeles I was immediately branded a psycho.
It is only in adventure that some people succeed in knowing themselves - in finding themselves.
