So here is the final entry in the island man scans. Yes, I gave up. I felt I didn't need to do it anymore, that I had achieved what I wanted to achieve. Or I felt I COULDN'T do it anymore, because it was sapping my life, the whole ten-pages-a-day self-flagellation thing.
I continued to write the book though. I even continued the page count in a word document for a while. Not sure how far I got, somewhere in the 4000s. And then I spent a long time typing it all up, sitting on the sofa alone in my flat after the dissolution of the relationship.
It's in a semi-readable form now and though I have written quite a lot since, I think it's probably the best thing I have written.
