What does this have to do with novel writing? Working backward may help with novel planning.
Every novel has a similar structure. One of the easiest blueprints to follow is Blake Snyder’s Beat Sheet from Save the Cat. If I know, for example, that my character must make a choice at the beginning of Act 2, then I can put that into my outline, early in the planning stages. I don’t have to plan the novel in chronological order or figure out all of the events that influence or lead up to the decision. The next time I outline a novel, I’m going to fill in the bones first, then flesh it out. I may even begin with the “Dark Night of the Soul” and work toward the beginning.
