To be able to endure odium is the first art to be learned by those who aspire to power.

He who has great power should use it lightly.

Those who boast of their descent, brag on what they owe to others.

There is no person so severely punished, as those who subject themselves to the whip of their own remorse.

Most powerful is he who has himself in his own power.

That is never too often repeated, which is never sufficiently learned.
