How do measure success ? I was asked. “You don’t,” I said.  “For once you look for a measure of success, you are in a trap”. For success is relative. Other people’s failures become your successes. And vice versa. ” Then when do you know your’e successful ? You have spent half a century on earth and still struggling. ” When you do not suffer from the illusion of controlling anything. And then you sleep well at night, which I do.”
