I’ve spent so much time over the last couple years at nitpicky editing that I practically enjoy it now. It’s the rewriting/changing things/adding things in that I just can’t stand. But then it’s somewhat similar to what GB said too–if I change something in book 1, I have to be very careful it doesn’t throw a monkey wrench into the plot of book 2 or 3. But then, I’m horribly anal about consistency.
And yes, some of the stuff I wrote years ago and have reread dozens of times does feel obvious, but I have the feedback from online friends to show me that it’s an issue of simply looking at it too often.
I’ve gotten very good at self-editing over the years, and found ways to help myself out. One is reading aloud (a good idea with helping dialogue anyway). Another is simply changing font and layout as sometimes I have things memorized by where they fall on the page. Anything that helps me see it from a different angle, or ‘tricks’ my brain into spotting things it might have missed. π
Good luck with that book! The oldest of mine I finished in 2001 when I had so much less experience than I do now is the one that really gives me the most misery with editing and tweaking. π
