Simply this: you sit down and make a list of the ten things that have to happen in your novel—the character actions or physical events without which your story simply cannot occur. Then, when you’re sure you’ve got pretty much the ten major “event beats” or character issues nailed down, you break each of those ten things into its own section and list the ten things that have to happen surrounding that event or supporting that character action. You take your time over this work, because this is the skeleton of the body of your work to come—the physical / emotional / action structure on which you’re going to build your novel.
