Yes. The dissertation is all over. 15,842 words plus bibliography. It's very strange having completed it - I feel quite blank and empty, and also convinced it's complete rubbish.
I once heard Sting say he never completed an album, he only ever abandoned them - there are always more overdubs you can do. Sting, I'm not, but I feel I have abandoned this. There are always some more edits you can do, but it's going in warts and all. I can be a normal human being again (well as normal as I get)
