Rewrite

I awoke this morning with a vision that my book was not finished. This is obvious as I'm only one 5th of my way into the A Nation lost. Then it must be my first novel Purple. Some people tell me they rewrite there books eight even ten times before feeling a little satisfied. I have only done this five times. So I have made myself a promise. Is that in the down times when i am slow on words for A Nation Lost, I shall rewrite Purple chapter by chapter page by page. I am strangely excited by this, can I make the prose tighter? I know I can. Can I make it flow smooth? Yes. Should i just leave it and move on, Am I a fool for trying this? Maybe but I have learnt so much going over my stories and my novel that I can only believe that this is helping me be a better writer. After all this comes from within us. In the end it is us that have to say we are finished.
