Why Didn’t I Think of That?

I had just dipped into a collection of Paris Review interviews with writers* when I came across this gem in the introduction to the interview with P.G. Wodehouse:

“All of which is by way of saying that Wodehouse, who lived four months past his ninety-third birthday, had discovered his own secret of long life: he simply ignored what was worrisome, bothersome, or confusing in the world around him.”

Brilliant! Why didn’t I think of that?
