Those who preach to princes so circumspect and vigilant a jealousy and distrust, under colour of security, preach to them ruin and dishonour: nothing noble can be performed without danger. I know a person, naturally of a very great daring and enterprising courage, whose good fortune is continually marred by such persuasions, that he keep himself close surrounded by his friends, that he must not hearken to any reconciliation with his ancient enemies, that he must stand aloof, and not trust his person in hands stronger than his own, what promises or offers soever they may make him, or what advantages soever he may see before him. And I know another, who has unexpectedly advanced his fortunes by following a clear contrary advice.
