>>281384749I've only been writing for a few years myself, but I have a complete roadmap/synopsis of my entire series written out, and it goes on for about 28,000 words.
The problem is that as I write more and more, I end up going in and changing certain things, either because I thought up better ideas, my editor suggested I change certain plot developments or story elements, or because I simply changed my mind. The story outline I wrote back in 2023 is vastly different than the one I have no.
Example: in 2023, I had an entire segment where the protagonist and antagonist would go to a dimension analogous to heaven and basically fight God and the archangels (more specifically, the antagonist fights and defeats them, and the protagonist tries to stop him but is too late). In 2024, I decided this was retarded and didn't fit the overall theme of the story, so I reworked it into something more thematically consistent with the rest of the series.
