Trading wisdom from 2,400 years ago

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.
