The drawback to that is that each time I reread it, I change the plot around for what's still unwritten. The good part about that, though, is that if I keep writing, the replotting posibilities get narrower the further along the story I get. For example, I had 'killed' off a character but was planning to let him survive and come back later. But then I was struggling with what exactly to do with him then, since I'd be introducing other subplots.
Looks like he'll be staying dead.
