There are no part time writers. It is not a hobby. This is not a dress rehearsal. I don't give a damn about what you got on your 11th grade book report. I've written and probably sold more than 20 screenplays.
Screenplays are short, compact, and intense.
Novels are fluid and open. Everything is research, research, and the hunt for tiny and important details is exhausting. It's a big book but not as much fun as my contemporary novels. The Edgar Cayce Story with my San Francisco class. But 1906 takes up most of my time.
