I think in the end, the trick is to diversify. A lot of writers that I've seen who are earning a comfortable income start with one book, get fans and do a series. They add more series. They help with editing. They do book and blog tours. They work on screenplays and script writing. They've done editorial writing. They've done how-tos and non-fiction help articles.
Writing one or two books, no, I don't think you can make a living that way. But if your goal is simply WRITING, you can, it just takes having your fingers in lots of pots. Many places are looking for freelance writers for articles and things too, so you can do that. Humor websites are always looking for articles. There are tons of ways to write and make money if you're willing do lots of things instead of just ONE thing.
