With stand-up you meet almost constant rejection. You put yourself out there with your thoughts and your ideas, and you think they're funny, and you hope other people think they're funny too. The only way you're going to find out is when you do it and what the reaction is going to be. So if you're not prepared for that, if you're not willing to go along with that, it's going to be a rough road. But beyond stand-up, in terms of auditioning for acting roles, you don't get most of the roles you audition for - you get a precious few.
