I stopped the class and asked, "Who were the first 5 players to get across the mat that time. Everyone's hands shot up and there was a chorus of, "me! me!" Then I asked, "Ok, of you guys who got across the mat fastest, who placed in the shiai last weekend?" All the hands dropped and the chorus died out. "Knox," I said, pointing down the mat at him still trying to complete the drill. "Slow Knox placed second."
The moral of the story: Slow and steady wins the day.
