Even though I have not yet tried to get a publishing deal, I seem well are that the publisher may want to change some things about my story, or ask me to change them. I made a lot of hard and careful decisions of what to add to the memoir and what to delete from it. Now I'm waiting to see how much I will want and need to add to the diary novel and what do delete, though there currently isn't a lot to delete--or there'd be no story at all! I have yet to even go thorough the diary to see what errors I have made (and I know I made some!), and I'm still struggling with the title. And there will be some polishing to do. Also, I am now wondering of I need to go over the memoir any more.
I now feel prepared to negotiate with my eventual publisher on what to add or delete, and what to title my works, should they not like what I choose.
