My film school is making movies. But, I do think that being an actor has served me immensely, as both a writer and director, in terms of knowing what is playable and what will be fun to play, for actors, and also how to communicate to actors on set, and not screw them up and get them in their head.
I feel lucky. I do love it, mostly. At college I had it in my heart that I wanted to be a writer but I didn't want to tell anyone about it. Then I graduated and became a bartender in Philadelphia, writing during the day. I was the worst bartender in the world.
