My ideas mostly come from the fact that I have little people living in my head telling me what they do all day, and if I don't write it down I think I might go crazy.

Nebulous plots tend to form around clusters of characters, and I then have to wrangle said plots and characters into something coherent. Sometimes it works, sometimes I throw it in the 'oh god why' folder and never open it again. I didn't used to bother planning out where I'm going, but I've realized that I HAVE to or everything goes in the OGW folder.
