I've been struggling with a novellaish thing that was supposed to be a short story for several weeks now, mostly due to the fact that I didn't have a clear idea of the story when I started. At the rate that I had been going, it was impossible to imagine how someone could finish and submit a short story each and every week, as I hear some of the more prolific writers have done.

To my great surprise however, yesterday I had an idea for a story that went the other way. I sat down to write, and some 3-4 hours later I had a finished first draft of about 2,000 words. How the hell did this happen? So, what are your experiences? What's the fastest time you ever finished a draft?
