When an archer shoots for enjoyment, he has all his skill; when he shoots for a brass buckle, he gets nervous; when he shoots for a prize of gold, he begins to see two targets.
ZhuangziThe Tao has no place for pettiness, and nor has Virtue. Pettiness is dangerous to Virtue; pettiness is dangerous to the Tao. It is said, rectify yourself and be done.
ZhuangziIn an archery contest, when the stakes are earthenware tiles a contestant shoots with skill. When the stakes are belt buckles he becomes hesitant, and if the stakes are pure gold he becomes nervous and confused. There is no difference as to his skil.
