I don’t really have much advice.😄. I’m a panster, so I have a lot of random stuff all over the place. I have a computer folder for each of my WIP’s, and ones for characters, author stuff and reference photos, but other than that, it’s usually all in my head.
One thing I’ve found is that if I don’t keep it, or I don’t remember it, then it’s usually not that important for the actual storyline. If it’s important for story, I remember it.
Other than that, all is chaos in my corner.🤣
Not all those who wander are lost.
