Thanks, guys.
The hardest part, actually, was making the decision that I was giving up on it as a novel. There are some novels that are very trunked and I wouldn't resurrect them in any shape (although, I say that, but the original novel I just wrote into a short story was based off a single chapter of a very trunked novel), but the ones where I had some success querying--just not enough--are hard to give up on.
People convinced me that even if I made it a short story, I'd have plenty of room to rewrite it as a novel again later (something I'm not so sure about, considering that some key scenes were ripped right from the novel), but now that I've done it and included a lot more of what I love than I thought I'd be able to, I realize that I like it better this way.
