Writing, Editing, and Revising

As I try and finish my first draft of Book No. 2 (which I'm starting to worry will forever remain untitled), I realize that I am less of a "writer" and more of a "reviser."  I think this is due in part, to the fact that the way I write is to not stop until I've hit 1,000 words for the day.  Some days/nights when the words and scenes are flowing well, this means that I easily hit more than the goal.  Other days, it's a struggle simply to reach the 1,000, but I know that regardless of how many words I leave on the page for the day, I know that I will always return to the page during the rounds of edits/revisions and will revise the paragraphs, often somewhat extensively.
