I didn't have a problem with rejection, because when you go into an audition, you're rejected already. There are hundreds of other actors. You're behind the eight ball when you go in there.
If I am told to be at a shoot at 10 A. M. , I am ready on time. By 11:30, I lose my patience. After that, I keep threatening to leave the sets if they don't begin soon. It works sometimes.
