Many people believe that fortune controls everything, so that there is no use in trying to act, but fortune controls only half of one's actions, leaving free will to control the other half. Fortune can be compared to a river that floods, destroying everything in its way. But when the weather is good, people can prepare dams and dikes to control the flood. If Italy had such preparations, she would not have suffered so much in the present floods.
Princes are successful one day and ruined the next, with no change in their natures. Two men may use the same method, but only one succeeds; and two men may use different methods, but reach the same goal, all because the circumstances do or do not suit their actions. If a man is successful by acting one way and the circumstances change, he will fail if he does not change his methods. But men are never flexible enough to change, either because their natures will not let them or because they become accustomed to a certain behavior bringing success.
It is better to be bold than timid and cautious, because fortune is a woman, and the man who wants to control her must treat her roughly.
