On the Need for Timely Wisdom

At 92, I’m wiser than I was when I was when I was 20, or even when I was 50, or even when I was 80. Whatever wisdom I have now could be condensed to a few basic principles that could be expressed on about half a page. Why didn’t I learn them by the time I was 20? For the felicitous playing out of future human history, we need to have more people getting wiser at an earlier age.
