Any good writer will have a lot of unfinished work. I have at least 150K works of unfinished, unpublished work, that will never see the light of day. In part because I changed direction in my business. In part because, while the content was good, thousands of others have said same. In part becasue I had to write it, just as much as I need to breathe to live.
But I keep it all. Sometimes I wish I could do something with it, but I think of it as foundations. I had to write all those words, to get to where I am now.
Not all art sees the light of day… and that is a good thing! :-)
