1. CHARACTERS – The cast of beings that feature in the story.
2. EVENTS – What happens to the cast.
3. WORLD – The environment and society the story unfolds in.
4. NARRATION – How you describe the above.
That’s it. Everything to do with the telling of a story goes into one of those four categories; character profiles, philosophies and motives fall into the first bucket; anything to do with plot, sub-plots, conflict and tension goes into the second; big-picture concepts and excruciating details of the world are lumped in the third; and directives concerning point of view, voice and inclusion and exclusion are placed in the last.
Obviously, I have yet to try this approach out in real life. But judging by the excitement that met the apparition of the idea it seems like a good way to get started.
