is it sometimes fustrating to be a professional actor?

Oh, Marla! Yes! It is often so frustrating to work in theater. There are so many people trying to audition for each role, and there are so few roles available. I'm always frustrated when a big role I'm passionate about goes away, or when a show folds. It can be incredibly frustrating. That said, there's a real rush when it all goes well. I just wish it were more often. Are you self-driven? Can you handle rejection after rejection and still show up with a smile on your face? Do you find your happiness from within? Acting can certainly be frustrating. You need to know that up front.
