As previously noted, it's easier to get through this if I remember that the copy editor and I are on the same team, with the mutual goal of producing the best book possible. That said, I still don't enjoy the corrections and wordsmithing. Some things just have to be endured as best one may to reach long-term goals.
On the brighter side, I've submitted another book proposal based on previous correspondence with the "Racing Royalty" editor. Wish me luck in getting my new project started!
