I just remembered something, too. I don't know if this is just a me thing or what, but I tend to think to music (why I don't always like pop music). I don't know why, but for some reason whenever I'm driving and thinking about a story (about 90% of the time) I kind of create like a minin music video in my head out of my story and edit it down to match the pace of the song. Then, when I hear the song later I can associate the story with it and kind of work on it in my brain. Also, I listen to the same song on repeat a lot, so I can really get going with that...
Might be just an obsessive me-thing.
