Progress Report -- Back to the Manuscript

About two months ago I emailed my completed manuscript to my publisher.  Yesterday, it came back with notes and edits. 

So it's back to work. 
7th annual Authors Fair in La Grange, Ky.I must admit that I was kinda enjoying the break from the manuscript. I attended three book-signing events in April, selling a few books, expanding my network with other authors, engaging new readers, and making a few friends. 
I haven't opened the documents. I told my editor that it will probably be a few days before I delve into the contents that contain edits, suggestions, and grammatical and typo fixes that should tighten and strengthen the story. 
So why haven't I started the editing process? 
I need to be in the right frame of mind. It's not something that I can do for a few days, take a few days off, and go back to it. Once I get started, I go from beginning to end. I have to stay focused. I find it mentally exhausting, even though I know there will be a degree of exhilaration when it's over.
The novel, a sequel to "Old Ways and New Days," is scheduled to be released on Nov. 1. I don't plan to sit on the edits very long (maybe a day or two) because I have other things to do between now and then, such as work with the publisher on a cover, marketing and promotion. 
And once I finish the formal editing phase, which includes reviewing the galley proof,  I plan to start on the next book in the series. So I have lots to do. Now to get focused.
Until the next time. . . .
