A quick question for my writerly friends...

What is your process for editing a very rough draft? I feel as though I'm editing in circles. I rewrote the opening chapters so I rewrote the next four chapters. In rewriting those I changed some things and then re-rewrote the opening chapters and then had to rewrite the next four... the snake eating it's own tail is still in my house.

What is your process for editing? In detail please, because I clearly need a system and I don't know how to do this. Previous to this book I've only written short stories so editing was a very different beast. I just rewrote everything over and over until I liked it. This requires being more systematic but I don't know how to begin.

HELP!
