What this blog lacks is a final conclusion. I will provide one now.
There are things in life that one can call "unfinished business". In my life I had two which stood out: fishing and playing chess.
I hardly caught any fish when I started to experiment with fishing.
It took me 25 years to get the hang of it. At the moment I understood how to do it and started to catch lots and lots of fish, I abandoned fishing. Since I don't like fishing. Experimenting and finding out how it works was a definite challenge, but when the challenge was over, it was finished. I never touched an angling rod again.
I made a genuine effort to get substantially better at chess. I failed. The final conclusion is that the common belief that you can become good at anything just by willing it and working hard is not true. No matter how intelligent you are.
I learned lots and lots of things about the workings of my own mind, so I don't consider it a waste of time. The lessons reach way beyond chess.
What is left is a monument of which others can take advantage. You can save yourself an awful lot of time by reading this blog well.
Good luck to all of you.
