Tonight, within the space of an hour, when I thought I had no more stretch to stretch, I ended up being stretched a little.
My son gave advice on how to scrape the deck, played "corral the ball with the skipping rope" (just like a horse) and invented a version of badminton, meticulously soaked his head with the water in a coke can over the sink and planned in minute detail how to make a hanging spider out of a ball of string. He moved effortlessly between these tasks.
I thought, man, I sit all day at my desk. I manage people and send emails and orchestrate things over the phone and pay bills and negotiate deals and I am not nearly as productive as he is being in this one short hour. He is using muscles I never use.
