I saw this on The Errant Aesthete and had to re-post. I think you can also consider visual artists as the writers in this analogy.
“I wrote stories from the time I was a little girl, but I didn’t want to be a writer. I wanted to be an actress. I didn’t realize then that it’s the same impulse. It’s make-believe. It’s performance. The only difference being that a writer can do it all alone. I was struck a few years ago when a friend of ours — an actress — was having dinner here with us and a couple of other writers. It suddenly occurred to me that she was the only person in the room who couldn’t plan what she was going to do. She had to wait for someone to ask her, which is a strange way to live.”
