The Art of War

Sun Tzu said:
"In general, the best method for using military force is to conquer an entire country intact; to destroy the country is inferior.Ancient warriors who knew how to use military power defeated the enemy, but not by fighting a battle. They overpowered the enemy, but did little demage in the process. The goal of military strategy is to take things whole. In this way, soldiers are not killed and wealth is preserved. Therefore, a general who wins all his battles by destroying other armies is not the ultimate warrior.The ultimate warrior is one who wins the war without fighting any battles.
The best use of military power, then, is to use superior positioning to force a surrender. If this tactic fails, use dilomacy.After that, use military power as a threat. As a last resort, attack your enemy."

This words have lots of meanings, and can be used not only in the principles of war, but in daily life also. First of all you have to establish if you have enemies, rivals, or just people you conqueer with. Secondly - play fair, and try to learn as much as you can from people that really know what does the word "war" mean....
For exemple, Sun Tzu is a semi-mythical figure who lived in China about 2,500 years ago, around the time of Confucius. Drawing on experience gained while leading succesful military campaigns, Sun Tzu developed and handed dow a collection of concise and immensly useful concepts governing the art of warfare, the lately were transcribed into a short book "The Art of War", that became a worldwide management phenomenon.
