[G]reat players and great companies don't suddenly start hunching up, grimacing, and trying to "hit the ball harder" at a critical point. Rather, they're in a mode, a zone in which they're performing and depending on their "game," which they've mastered over many months and years of intelligently directed hard work. There's only so much thinking you can isolate and focus on during that kind of extreme competitive pressure. It has to be tactical more than a conscious effort to really "try harder." You just want to function very well, up to your potential, effortlessly—do what you already know how to do at the level of excellence you've acquired—whether in making a presentation or coaching a game or anything else. Bill Walsh
