In every human endeavor there are two games of engagement: the outer game and the inner game. The outer game is played in the public arenas of daily life, overcoming obstacles in work, family relationships, and health. The inner game is played simultaneously within the mind against such obstacles as fear, self-doubt, frustration, pain, and worry, which produce stress and stifle fulfillment. When we master the inner game, we can handle the obstacles of the outer game without stress.
