From Seth's blog:
In the infinite game, though, something completely different is going on. In the infinite game, the point is to keep playing, not to win. In the infinite game, the journey is all there is. And so, players in an infinite game never stop giving so they can take. Players in this game throw a slower pitch so the batter can hit it, because a no-hitter shutout has no real upside.
Joy is found in the journey. The destination isn't the goal. Be in it for the infinite game.
