When I was 20 I work with a bunch of guys in their 40s. As I raced about and rail about they would shack their heads. What? You’ll see. See what? Then they would walk away laughing. As I approach the edge of 60 I’ve had 40 years to ponder why 40 can’t transfer wisdom to 20. For the longest time I thought it was matter of not being about to hear or even listen. But it was really something more subtle. It was the inability to see the trip as infinitely more rewarding that the arrival at the destination.
