What advice does machiavelli offer to a prince? give at least four examples

He tells him that a state that has a sole prince for a ruler is difficult to conquer, but one who has a prince who shares power with a baron is easier to conquer, but far more difficult to maintain. A prince should always try to create his rise to power on his own attributes and work, not that of his friends or luck because holding onto power is a difficult task. A prince should not rely on mercenaries and auxiliaries for troops, he should have good foundation of strong laws and good arms and it can survive, mercenaries are disloyal and armies can become loyal to another master. Reputation is key, a prince should be a good liar who puts on one face for his populace and one who is the real him, one should not do things to just appear generous though, it is better to be a feared leader than a loved one.
