When an archer is shooting for nothing
He has all his skill.
If he shoots for a brass buckle
he is already nervous.
If he shoots for a prize of gold
he goes blind
or sees two targets-
He is out of his mind!

His skill has not changed. But the prize
Divides him. He cares.
He thinks more of winning
Than of shooting-
And the need to win
Drains him of power.

- Chuang Tzu
