There's a special kind of supervillain in the first season of the Netflix show "Jessica Jones"; a man who can dominate the will of other people, at least for a couple hours a time. His life is dull, since he gets everything he wants, which is plausible and tells us that the ability to control others like that is hardly a sensible wish.
The opposite, laying out assumptions, facts, reasoning, conclusions - only to achieve absolutely zero effect (in private, business or public affairs) all too-often - is not exactly fulfilling either, of course. It's particularly frustrating if you can tell time and time again that even if someone has read your report, your article, or listened to your argument, he or she may still be 100% unaffected and stick to a different preferred answer without the slightest ability to support it with facts and reasoning the way you did.
Back when I was about 20 I looked at all the nonsense in the world and thought that the world could be improved if one would only cut through the nonsense with knowledge, logic and some inspiration.
Back when I was about 30 I amassed the confidence in knowledge, logic and inspiration to begin trying to disseminate it for real. Professionally and in matters of public interest publicly.
Now I understand that for decades I underestimated one huge and all-important ingredient; the ability to convince. Sadly, this ability is given to or found by people irrespective of the quality of knowledge and reasoning. Some utter sociopaths, people with narcissistic personality disorder and lots of people who simply don't have the well-being of others (or even their entire society) in mind possess a greater ability to convince people than most genius researchers with great ideas.
So here's the update:
It takes a coincidence of philanthropy (or at least social leanings), knowledge, reasoning, some inspiration and the ability to convince others easily to improve the world by much. Well, this or another kind of huge luck.
Now it's abundantly clear to me why the human world is such a mess in so many places and perspectives. It may take a couple thousand more years till enough such coincidences have happened. And then there will likely still be some *#%$€=(! with the gift to convince and mess it up again.
