And the important thing is that you should stand up for your privileges. When someone says, "Lucy, it's really great that you got that role. Your Dad knows the Producer doesn't he?" - you can respond in one of two ways---
Often these people have the same privileges too. And you wanna dive in and say "Hold on, you're 42 and live with your parents.. and... and..." But then, there's really no need to justify yourself. They'll say "yeah but I have car payments to make, and don't forget, I have a girlfriend." Of course, the thing to realize is that the car was a choice, and the girlfriend was a choice. Instead, you made the choice to pay a crew to shoot your movie, but they don't see it like that.
