Well, we are close to the second anniversary of the pandemic, so the novel is two pandemic years old. I guess one year was the outline and one was the first draft?
The second draft is half done in six weeks. If a draft takes 3 months, and I have 17 drafts, that's 51 weeks. (Though, half of the 17 drafts are things like "check if it really was a full moon that day.")
Of course, after the 17 drafts it'll just be good enough to show to writing groups.
Will I have forgotten to play the guitar by then? That's the real question.
