I recently restarted MS #2. It's been a hard road, coming back after a few months of not doing anything on the story. And what I reread, I didn't like. The plot was there, but that was about the only thing good about it. I know I'm going to have to rewrite it. But for me, I have to complete the MS first, so that I can see everything more clearly before I started rewriting.
But just getting to the end is the hard part. I'm 35k in of 50k. (My first drafts tend to be short). And every word is a fight. It's hard to be motivated when I know I just have to rewrite the thing. But I know it will be better if I just finish first so that the whole thing can make sense in my brain. I have big plans for rewriting and revisions, but I just have to get to that point.
I think I need to go back and reread some stuff from SAVE THE CAT! (Seriously, if you don't own this book, you totally should!) And next time, spend more time outlining before diving in to writing. I do simple outlines with major points and stuff, but now I see why detailed outlines are so helpful! (Why hadn't I seen it before??) But as long as the MS gets completed, I'm going to call it a winner. For now. (Until I get to revisions...)
