The last few nights, I've been sitting up late, working on my book. At last I finished reading it, and then I went through highlighting passages, and then compiling a lo-o-ong list of questions for my detective neighbour.
So I'm far too tired tonight to do more than write a quick blog to say: amongst all the observations I could make about my own work (and probably will), one of the most encouraging is: the later chapters were much better than the earlier ones.
I'm taking this as proof that I am learning and improving, even without any critiques or feedback. And that means my potential for further improvement need only be limited by how willing I am to learn and to practise.
