If you realize that all things change, there is nothing you will try to hold on to. If you aren't afraid of dying, there is nothing you can't achieve. Trying to control the future is like trying to take the master carpenter's place. When you handle the master carpenter's tools, chances are that you'll cut your hand.
LaoziThe man of knowledge acquires something new everyday, and the man of Tao lets go of something new every day.
LaoziThe 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.
Laozi
