Status update of my WiP

So this week, I finished the 4th draft of my WiP, and boy is it starting to make more sense. I still have to go back and start implementing more backstory and setup a few things differently that weren't working via my beta readers.

I read somewhere recently that the real writing is during this rewriting, and have to say that this is true. I am excited to really get back into this story now that I know it works on the basic story level.

So what are some of your strategies for rewriting? Have you ever found it more fun to do a revision than the first draft? What was one of your favorite things to come out of a revision?
