I have been reading the Art of War, a fascinating piece of literature that discusses the art of strategy and preparation for battle (and life). I recently pondered the teaching below:
"Throw your soldiers into positions whence there is no escape, and they will prefer death to flight.
If they will face death, there is nothing they may not achieve. Officers and men alike will put forth their uttermost strength."
In this quote, General Sun Tzu discusses his strategic decision of giving his soldiers no escape route.
Taking away his men's escape gave his army only one possibility: forward.
