A writing journal is a good idea for a jumbled mind. Everytime I have some spare time I sit down and read my last entry, just to see where I left off. Then I write about my characters, plots, story ideas, villians, and sometimes an inspirational quote. Sometimes I write down certain scenes that are unrelated to any story I’ve so far written or a scene of a story that hasn’t progressed that far yet. I can turn back to those and use them or elaborate on them when the need calls for it. If you don’t like to write free hand use a computer instead. Personally, I like the change of pace. Writing free hand is more difficult because your hand gets tired, so you won’t be writing for a long time and it won’t be as wordy because its just you writing to you (and there’s no automatic thesarus!)
