Chinese military strategist.
"The "Sun Tzu Art of War" explains the theory of managing soldiers and is still widely in business, economy, and military affairs."
If you know the enemy and know yourself, you need not fear the result of a hundred battles."
The quality of decision is like the well-timed swoop of a falcon which enables it to strike and destroy its victim.
"The general who advances without coveting fame and retreats without fearing disgrace, whose only thought is to protect his country and do good service for his sovereign, is the jewel of the kingdom."
To fight and conquer in all your battles is not supreme excellence; supreme excellence consists in breaking the enemy's resistance without fighting.
