If you are a trader, you will relate

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, 400 B.C..

If you do not relate, then you are not likely a trader.
