And yes, I said retyping. I sometimes have a hard time making myself do it, but I find that the most effective revision method for me involves actually retyping the text; I'm much more likely to make real changes that way, and it improves the story immensely.
I think I retyped Bodies in Motion four times in total. Hopefully, this book won't require quite that much typing!
I can relate. I have to rewrite math papers by hand several times to get the prose to flow properly.
