Ok, so I thought of a great revision for one of my novels that would give me the opportunity to have a much better opening, plus would tie a major villain to my character. Because I still have a full manuscript out on submission, I made a copy of my manuscript before I made any changes.
And I proceeded to pepper the manuscript with changes. Too late, I realized that I should have turned on my "track changes" feature, but I gave a mental shrug. I resolved to find some sort of tool that will show the differences between two Word docs. (Surely such a thing exists.)
Then, on the way to work this morning, I realized that my great revision will not work. At least not without a lot of changes. More changes than I am willing to make, at this time, and changes that I'm not even certain will work in the long run. I'd hate to rewrite the novel backwards, then discover that it just ain't working.
So I'm glad I took that backup before I started. Have you ever done this?
