|Often I write in my head. Actually, I constantly write in my head, so when it comes to getting it down it might be the thrid or fourth 'draft' IYSWIM.|
I'm the same. Everything that goes through my mind is part of my writing, one way or another. Because of that, I finally decided, a few months back, on the direction to take with my blog. Which is, that it's all about writing but through conversations with people in my street or wherever I happen to be, or sometimes just with myself. I feel that as soon as a writer goes into 'advice' mode, they're in danger of switching from organic-in-the-process-all-the-time to voice on a stick, basically.
What you say also, I think, explains why the work of those who produce gallons of stuff without much pre-thought often reads competent at best, dull and predictable a lot of the time.
