I've never thought of myself as a writer. Yet I've just finished ghostwriting a course. I guess I've written between 500,000 to 1,000,000 words for myself and others. That's an incredible number. I thought about what it means to be a writer while reading Chuck Palahniuk's book on writing. Though there exist many subsects of writers, I'd like to think of a professional writer as someone who writes for a living. So I am a writer.
