Every now and then it's nice to stop and just look over what you've been writing and the way you've been writing it and sort of reassess it, and see if you've fallen into bad habits or there's something you'd like to get better at. One way of reexamining your own work is to work with somebody else. It's a learning experience. I don't want to get into a rut.
