I wrote for free for, like, fifteen years; I could redo my parlor in rejection slips. It would be surprisingly tasteful - they use nice paper.
I've found I can plunge the characters into whatever absurd, awful situation, and readers will follow as long as the writer makes them seem like 'real people.'
I used to be a model and a medical test subject, though never at the same time. And since we didn't have much money when I was a kid, I know how to fish and hunt for my supper. And I used to win awards in speech in high school, which comes in handy when I speak to 200 people at a writers' conference.
