In war, numbers alone confer no advantage. Do not advance relying on sheer military power.
Luoyang, China
Water shapes its course according to the nature of the ground over which it flows; the soldier works out his victory in relation to the foe whom he is facing. Therefore, just as water retains no constant shape, so in warfare there are no constant conditions. He who can modify his tactics in relation to his opponent and thereby succeed in winning, may be called a heaven-born captain.
Force has no place where there is need of skill.
Speak softly and carry a big stick; you will go far.
Discipline is the soul of an army. It makes small numbers formidable; procures success to the weak, and esteem to all.
