To borrow a simile from the football field, we believe that men must play fair, but that there must be no shirking, and that the success can only come to the player who hits the line hard.
There was a long stint during my childhood after I gave up on being a pro football player - were talking sixth grade here - that I strongly considered a future writing and drawing comic books. I have been making stuff up ever since.
Without defeats, how do you really know who the hell you are? If you never had to stand up to something - to get up, to be knocked down, and to get up again - life can walk over you wearing football cleats. But each time you do get up, you're bigger, taller, finer, more beautiful, more kind, more understanding, more loving. Each time you get up, you're more inclusive. More people can stand under your umbrella.
How on earth can otherwise sensible people get so involved in a football game? You could measure the lasting impact on the lives of the people who played it at just about zero.
