The best athlete wants his opponent at his best. The best general enters the mind of his enemy. The best businessman serves the communal good. The best leader follows the will of the people. All of the embody the virtue of non-competition. Not that they don't love to compete, but they do it in the spirit of play. In this they are like children and in harmony with the Tao.
Of the second-rate leaders people speak respectfully saying, "He has done this, he has done that." Of the first-rate leaders, they do not say this. They say, "We have done it all ourselves."
The best soldier does not attack. The superior fighter succeeds without violence. The greatest conqueror wins without struggle. The most successful manager leads without dictating. This is intelligent non aggressiveness.
