I found Lisa Rowe Fraustino's post at Cynsations on The Benefits of Keeping Your Day Job particularly interesting because recently I read an article about a writer who quit hers after publishing her first book. She has a three-book deal and quit her job to write full time.
The article said her first title was published "to acclaim," but it isn't a title that's getting the buzz of, say, a Twilight or a Hunger Games. I wonder if this writer realizes what she might end up with for income these next few years.
I'm guessing not.
