One change always leaves the way open for the establishment of others.

Men may second fortune, but they cannot thwart her.

It makes him contemptible to be considered fickle, frivolous, effeminate, mean-spirited, irresolute, from all of which a prince should guard himself as from a rock; and he should endeavour to show in his actions greatness, courage, gravity, and fortitude; and in his private dealings with his subjects let him show that his judgments are irrevocable, and maintain himself in such reputation that no one can hope either to deceive him or to get round him.

All courses of action are risky, so prudence is not in avoiding danger (it's impossible), but calculating risk and acting decisively. Make mistakes of ambition and not mistakes of sloth. Develop the strength to do bold things, not the strength to suffer.

An armed republic submits less easily to the rule of one of its citizens than a republic armed by foreign forces. Rome and Sparta were for many centuries well armed and free. The Swiss are well armed and enjoy great freedom. Among other evils caused by being disarmed, it renders you contemptible. It is not reasonable to suppose that one who is armed will obey willingly one who is unarmed; or that any unarmed man will remain safe among armed servants.

There is simply no comparison between a man who is armed and one who is not. It is simply unreasonable to expect that an armed man should obey one who is unarmed, or that an unarmed man should remain safe and secure when his servants are armed.

For that reason, let a prince have the credit of conquering and holding his state, the means will always be considered honest, and he will be praised by everybody because the vulgar are always taken by what a thing seems to be and by what comes of it; and in the world there are only the vulgar, for the few find a place there only when the many have no ground to rest on.
