You'll have to just draw a picture in your mind today, because I'm on the wrong computer and don't have my usual access to the wonders of free photography.
First drafts! I've written a lot of them in my lifetime. I've written many, many more first drafts than final drafts, and even turned in some first drafts as final drafts in my time (hey, I was in primary school; I didn't know that revision even existed back then!). For years I had this lovely lovely idea that Laura Wilder or Beverly Cleary wrote in exactly the same way I did-- start to finish, with everything "perfect" the first time.
Then I went to middle school and was disabused of such ideas. And now that I'm in contact with other writers all the time, any chance of such fantasies ever returning is blessedly nil.
But first drafts are fun, though. (Term used loosely; I do prefer revision.) Ideas flow from brain to page, unencumbered by such things as continuity. The muse, when she is cooperating, is hard at work. Words obediently line up into sentences that will later send me facepalming as I wonder what exactly I meant when I wrote "Greasy fingers aren't guitar strings". Vast quantities of caffeine are consumed, bedtimes are ignored, showers are optional, friends give up at attempting reasonable conversation.
It's wonderful. And then you can shove the whole thing in a drawer and not worry about it for a couple of months.
Is writing a first draft (of anything; doesn't have to be a novel) exhilarating for you? Or do you prefer revision? Editing? Share your writing preferences here.
