Depends on the day. I’m a “recovering pantser” which means that by nature I prefer to sit down at the keyboard and see what happens. Unfortunately, as a method to write a book, that one’s slow, convoluted, and frustrating. So I try to outline at least the basics, even if I change my mind as I go, and some days I obsess over plot points. Others, though, the words flow and the magic happens. Those days are precious.
