Quod Principi plaevit habet legis vigorem - Niccolò Machiavelli

A prudent man should always follow in the path trodden by great men and imitate those who are most excellent, so that if he does not attain to their greatness, at any rate he will get some tinge of it.

It's better to be feared than loved if you cannot be both.

It is truly natural and ordinary thing to desire gain; and when those who can succeed attempt it, they will always be praised and not blamed. But if they cannot succeed, yet try anyway, they are guilty of error and are blameworthy.
