how do you become someone like..

Bill oakley, Josh Weinstein? (ah i don't know how to spell his last name..) i mean like, how do you become a .. supervising director, a writer, or someone who does voices on cartoons like mission hill or the simpsons. I'm guessing you have to work in ..uh.. some kind of class that teaches.. something similar to it, and go to college right? and get good grades on your classes. but then what? do you have to just hope someone who directs a show, finds you out and sees if your good enough to work on his/her show ?
most of you graduated or so i think, so i was hoping someone would know.
