Excerpt from here:

“In 210 BC, Xiang Yu led an army against the Ch’in Dynasty.  While his troops slept, he burned his ships and smashed all the cooking pots.  He explained to his troops that they had to either fight their way to victory or die.  His troops won 9 consecutive battles.  Eliminating options improved the focus of his troops.”

I like this Xiang Yu guy.
