Since my revelation on the road concerning the bomb in the closet, I have never hesitated to ask myself, either before starting the second draft of a book or while stuck for an idea in the first draft, just what it is I’m writing about, why I’m spending the time when I could be playing my guitar or riding my motorcycle, what got my nose down to the grindstone in the first place and then kept it there. The answer doesn’t always come right away, but there usually is one, and it’s usually not too hard to find, either.
