Honestly, I do a light‑weight map, like a roadmap with red flags for big events and a few open lanes for the curveballs. I keep a “spontaneity buffer” in the spreadsheet—just a column that says “random meme drop” and leave it blank until the internet does something wild. Then I jump in and tweak the whole thing on the fly. Keeps the vibe fresh while still giving me a cheat sheet when the trending wave hits.
