If the enemy has occupied them before you, do not follow him, but retreat and try to entice him away.
Sun TzuIf not in the interests of the state, do not act. If you cannot succeed, do not use troops. If you are not in danger, do not fight.
Sun TzuWhen the leader is morally weak and his discipline not strict, when his instructions and guidance are not enlightened, when there are no consistent rules, neighboring rulers will take advantage of this.
Sun TzuHe who wishes to fight must first count the cost. When you engage in actual fighting, if victory is long in coming, then men's weapons will grow dull and their ardor will be dampened. If you lay siege to a town, you will exhaust your strength.
Sun Tzu
