That's one of the challenges of acting. You can't expect that you're going to be successful, but you've got to put your heart and everything you have into it. Look at a guy like Ian McKellen, who is eighty or whatever, and he's just loving his work and you can see that in the work. That defines what type of actor you are. And what kind of people want to work with you. And whether you can do this job for a long, long time.
