I was getting a little ahead of myself, launching into a new book. There I was, happily diving into chapter two, when a note from my editor lets me know she suddenly has new "thoughts" about the last book. Thoughts = revisions. A second round of them. In other words, I have to get my head out of its happy new space and back into a state of mind that allows me to rip out favourite lines and scenes and moments from something I thought was "finished".
Sometimes (maybe all the time) being a writer requires serious self discipline.
