Tony Perez's Art of War: At the workplace, remain silent when someone unjustly criticizes you, plays a prank on you, or provokes you. Do not react immediately. Do not even argue and insist on having the last word. Instead, develop and improve yourself while engineering things so that the enemy eventually falls into his/her own trap and eats his/her own words.

Looking down at the lower status of your enemy and watching the expression on his/her face is one of the most precious moments in life.
