I finished my third round of edits on the 4th of July. (Yes, that's how authors who have full time jobs spend their holidays.) It felt like I revised about ten percent of the book. Most of it was minor, especially compared to the big changes I made the first and second times I went through the manuscript. I just started editing it for the fourth time. I'm pretty sure that after this round, I'll send it to some proofreaders to review because I'll need another pair of eyes to see the mistakes that my eyes are becoming blind to.
As I've mentioned before, I don't like the editing process. I'd much rather be writing something new than to comb through something I've already written for the umpteenth time. But I know that editing is necessary if I have pride in my work. I don't want to publish a sloppy story because I wasn't willing to work on making it better. That wouldn't be fair to my readers.So I'll keep going, probably for another two or three months, until I feel that the story is about as good as I can make it.
