The outline is as conflated as it’s likely to get for now, or until more inspiration strikes.
It’s time to start writing the story.
I’ll make a ‘safety’ copy of the actual conflated outline, and put it away.
I’ll start with chapter 1 and actually consume a copy of the outline as I go, so word count and page count will come and go as I lay down new words and erase bits of the conflated outline as I go. It’s a curious process, but it’s a lot better than facing pure white space.
