For the project I'm currently working on, I'm taking some pieces from a failed manuscript dating back several months ago. I would simply rework the other one, if I hadn't already borrowed from it for a different story. I like to pick the skeleton clean whenever I've killed a story. Completing and subsequently abandoning a project never feels as much of a complete waste of time if there is something to be salvaged. And so I wander through the wasteland of words, looking for scraps to weave into a newer vision that is always better than the first.
So far, the hunting has been good.
