the wise man should always follow the roads that have been trodden by the great, and imitate those who have most excelled, so that if he cannot reach their perfection, he may at least acquire something of its savour.

Never lead your soldiers to battle if you have not first confirmed their spirit and known them to be without fear and ordered; and never test them except when you see that they hope to win.

Make no small plans for they have no power to stir the soul.

The prince who relies upon their words, without having otherwise provided for his security, is ruined; for friendships that are won by awards, and not by greatness and nobility of soul, although deserved, yet are not real, and cannot be depended upon in time of adversity.

One can make this generalization about men: they are ungrateful, fickle, liars, and deceivers, they shun danger and are greedy for profit; while you treat them well, they are yours.
