Attack the enemy's strategy.

Being unconquerable lies with yourself; being conquerable lies with your enemy.

What the ancients called a clever fighter is one who not only wins, but excels in winning with ease.

When you do battle, even if you are winning, if you continue for a long time it will dull your forces and blunt you edge...If you keep your armies out in the field for a long time, your supplies will be insufficient. Transportation of provisions itself consumes 20 times the amount transported.

If you fight with all your might, there is a chance of life; where as death is certain if you cling to your corner

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.

When the enemy is at ease, be able to weary him; when well fed, to starve him; when at rest, to make him move. Appear at places to which he must hasten; move swiftly where he does not expect you.
