Writing is Rewriting

I've said that I finished my diary novel, but does when one really ever finish such a thing? I know I'll be rewriting it, however many times I feel I need to do so. When I said I finished it, I meant that I had gotten to the desired ending. 

This graphic says it all.

I have written my first draft. I have not looked over it for  a while, but I'm guessing I'm taking some time ways form the work to come back later with fresh eyes. Even though I have not worked on it for  awhile, I already know some things I can change and add. This was how I worked on the memoir, so I know now to do the same with the diary novel. I have also been thinking of what I can write for another book on the character introduced in my still-not-titled book. I got some suggestions, though and some great feedback from those who have read the story. I should try writing down the ideas for the possible second book, though I know I need to work more on the first one. Now I don't know what to do next! I guess whatever I want to do next.
