Writers: how do you pay the bills?

I saw this Salon article after attending a half-day nonfiction writing workshop at the big university down the highway. It was a modestly sized group made up of a variety of people, and for almost the entire session the conversation remained centered on the topic of writing. Near the very end, it spun off into tentative inquiries about publishing. Then always the big questions: Could my book be a bestseller? Could I actually earn some money off of this? Can I make a living off of writing?

In the Salon article, a couple of anonymous authors fudge the economic reality:

How about you? What’s your reality?
