As a competitive athlete throughout my youth, I used to wonder how Olympic medalists and various world championship teams could laugh lightheartedly during training camp and locker room interviews, especially before game time! Such levity and lack of seriousness seemed to defy logic, because the assumption is that world-class results come from hard work, sacrifice, and a kind of stoic, straight-faced dedication. You are supposed to enjoy exuberant, carefree celebrations only AFTER you have accomplished your admirable feat, after all!
