I've posted this link before, but for someone else, I think.
I'm a heavy outliner - I include all/most of the little side conversations and bits and bobs in my outlines, because I find that with that complete an outline, I can get up to 5-8000 words in a writing day. (The link is ugly, I'm so sorry.)
I know a lot of pantsers and plantsers, but I'm not one of them.
