“Whosoever desires constant success must change his conduct with the times.”

“And let it be noted that there is no more delicate matter to take in hand, nor more dangerous to conduct, nor more doubtful in its success, than to set up as a leader in the introduction of changes.”

“A man who is used to acting in one way never changes; he must come to ruin when the times, in changing, no longer are in harmony with his ways.”

“And it ought to be remembered that there is nothing more difficult to take in hand, more perilous to conduct, or more uncertain in its success, than to take the lead in the introduction of a new order of things.”

“But confining myself more to the particular, I say that a prince may be seen happy to-day and ruined to-morrow without having shown any change of disposition or character. This, I believe, arises firstly from causes that have already been discussed at length, namely, that the prince who relies entirely upon fortune is lost when it changes. I believe also that he will be successful who directs his actions according to the spirit of the times, and that he whose actions do not accord with the times will not be successful. Because men are seen, in affairs that lead to the end which every man has before him, namely, glory and riches, to get there by various methods; one with caution, another with haste; one by force, another by skill; one by patience, another by its opposite; and each one succeeds in reaching the goal by a different method. One can also see of two cautious men the one attain his end, the other fail; and similarly, two men by different observances are equally successful, the one being cautious, the other impetuous; all this arises from nothing else than whether or not they conform in their methods to the spirit of the times. This follows from what I have said, that two men working differently bring about the same effect, and of two working similarly, one attains his object and the other does not.”

“It must be considered that there is nothing more difficult to carry out, nor more doubtful of success, nor more dangerous to handle, than to initiate a new order of things.”

“I say that every prince must desire to be considered merciful and not cruel. He must, however, take care not to misuse this mercifulness. … A prince, therefore, must not mind incurring the charge of cruelty for the purpose of keeping his subjects united and confident; for, with a very few examples, he will be more merciful than those who, from excess of tenderness, allow disorders to arise, from whence spring murders and rapine; for these as a rule injure the whole community, while the executions carried out by the prince injure only one individual. And of all princes, it is impossible for a new prince to escape the name of cruel, new states being always full of dangers. … Nevertheless, he must be cautious in believing and acting, and must not inspire fear of his own accord, and must proceed in a temperate manner with prudence and humanity, so that too much confidence does not render him incautious, and too much diffidence does not render him intolerant.”
