The people who are bullying you, they're insecure about who they are, and that's why they're bullying you. It never has to do with the person they're bullying. They desperately want to be loved and be accepted, and they go out of their way to make people feel unaccepted so that they're not alone.
I give myself homework when I have an audition. I give myself goals, and that's how I check how I'm doing. It can be something simple like 'listen,' or 'find your feet.' And then afterward it's an assessment, so in a way it's not about booking the job or not. It's about what I learned as an actor about that character.
