Quote by Sun Tzu

“Victory can be created. For even if the enemy is numerous, I can prevent him from engaging. . . . [I]f he does not know my military situation, I can always make him urgently attend to his own preparations so that he has no leisure to plan to fight me. Therefore, determine the enemy's plans and you will know which strategy will be successful and which will not. Agitate him and ascertain the pattern of his movement. Determine his dispositions and so ascertain the field of battle. Probe him and learn where his strength is abundant and where deficient. The ultimate in disposing one's troops is to be without ascertainable shape. Then the most penetrating spies cannot pry in nor can the wise lay plans against you. It is according to the shapes that I lay the plans for victory, but the multitude does not comprehend this. Although everyone can see the outward aspects, none understands the way in which I have created victory. Therefore, when I have won a victory I do not repeat my tactics but respond to circumstances in an infinite variety of ways. Now an army may be likened to water, for just as flowing water avoids the heights and hastens to the lowlands, so any army avoids strength and strikes weakness. And as water shapes its flow in accordance with the ground, so an army manages its victory in accordance with the situation of the enemy. And as water has no constant form, there are in war no constant conditions. Thus, one able to gain the victory by modifying his tactics in accordance with the enemy situation may be said to be divine. Of the five elements, none is always predominant: of the four seasons, none lasts forever; of the days, some are long and some short, and the moon waxes and wanes.”
