As a friend of mine was on her way to a big audition I said, “Have fun.”
She said, “Ooh. That’s different. Thanks.”
It’s customary to wish an actor good luck by saying, “Break a leg.” I don’t know why and I don’t feel like asking Google. But I don’t like wishing people good luck anymore because it’s just that: a wish. You know what they say: If wishes were horses we all would ride.
Luck is arbitrary and out of our control. It can bestow its favors on anyone at any time or not. Anybody can get lucky whether they put in the work or not, whether they deserve it or not. (We make judgments about the latter all the time, don’t we?)
So you can’t depend on luck or conjure it up, but you can make up your mind to have fun. That’s your attitude, your decision.
When I audition, I can’t make them pick me, but I can choose to do my best work (whatever best means in the moment) and have a good time doing it. Why wouldn’t I? Why wouldn’t you?
