I usually write the first draft at home or in my office, at my desk, in the afternoons. If I’m really struggling, a change of location helps, so I frequent a local coffee shop. I must hide away and do my second draft in an empty office, because I read the whole thing out loud. I usually red pen a hard–copy of the third draft on an airplane, things arrange it so I’m always traveling at that point in the writing process. I used to go over the copy edits with my best friend on the couch in her living room with much companion hilarity, these days I'm usually too rushed. You can also see my blog post on the subject of my desk and bribery system.
