No man is so prudent that he knows how to adapt himself to this fact, both because he cannot deviate from that to which he is by nature inclined, and also because he cannot be persuaded to depart from a path after having always prospered by following it. And therefore, when it is time to act impetuously the cautious man does not know how to do so, and is ruined as a result; for if he had changed his conduct with the times, Fortune would not have changed.
