The right words

The book I am writing has three parts as most things in life do. The first draft of the beginning is finished and I have a fair idea of what I want from the third part but I am really struggling with the middle. Yesterday I wrote, I deleted, I wrote, I deleted again and again. (Deleting isn't quite right because as I write the first draft in long hand with a pen it was really I wrote, I crossed out etc etc but that's a minor detail.) Eventually after about two hours I had 100 words that I was happy with. At least they were the right words...I hope.
