Writing doesn't leave much time for hobbies, unless you consider that I began writing as a hobby and have made the hobby into a profession.
I had a friend in high school who badly wanted to make movies and would recruit me as an actor. It was always so much fun. I decided, I'm going to go to Hollywood and make movies, which is a thought I'd never had before.
It just makes everything more pleasurable when you've got someone that emotionally is there to rely on.
