First draft. Ahh, the first draft. The exciting, terrifying, wonderful, exhausting first draft. I’m a fast drafter, so this usually takes me anywhere from three and a half to six weeks, depending on the length of the WIP and whether or not I outlined. To me, this is in many ways the hardest part, because you are, in essence, making the clay that you will later refine into a polished story. Pre-first draft, all you have are a bunch of ideas, but post-first draft you have a novel.
An excellent outline of the process.
Get started, and keep going.
