The Publishable Piece

I'm in the process of finishing my publishable piece for law review (due on Friday). I keep adding and taking away and revising what I already have. Writing right now feels like trying to control the aperture on an old-school SLR camera: constantly finding and then losing focus on my subject. What am I trying to say? I hardly know anymore. But I do know it will be done on Friday, and my spring break can begin.
