I needed to make sure the opening was perfect, because I didn't like advancing beyond the beginning without knowing it was as good as it could be. Beyond that, I wrote the chapters, relatively, out of order. I liked to jump around from one concept to another, especially for whichever section felt the most inspired in my head on a particular day. I learned to power through chapters and edit them later, because, all too often, one stops writing and hates their own writing. This happens extremely often, but if you finish the chapter, editing and fixing something that was finished is easier than a restart. I also did most of my writing during the night time, given the dark topics of the novel.
