It's pretty easy to read a first draft and pinpiont what's wrong with it. It can sometimes even be simple to decide how to fix it. The hard part is getting your brain to move into fix-it mode and making those changes. It's a challenge, and it's rewarding once I get it done.
I worked on Sungard tonight, contemplating a name change to The Fallen Sun, but we'll see after I make it through this edit pass. I only got through 1.3 pages out of an orriginal 7 pages, and 1 page of that was new material. A few more nights of this and I should be able to make it through safely. ;) I'm looking forward to getting it all fixed!
