Politeness is the chief sign of culture.

Do pleasant things yourself, but unpleasant things through others.

Attain and maintain a reputation, for it is the usufruct of fame. A stiff climb, for it is the issue of excellence, as rare as mediocrity is common.

He that has satisfied his thirst turns his back on the well.

There is none who cannot teach somebody something, and there is none so excellent but he is excelled.

There is no need to show your ability before everyone.

The hossanas of the multitude can never bring satisfaction to the discerning. Yet there exist those chamaleons of popularity who find their joy, not in the sweet breath of Apollo, but in the smell of the crowd. And not in mind: Do not be taken in by what are miracles to the populace, for the ignorant do not rise above marveling. Thus the stupidity of a crowd is lost in admiration, even as the brain of an individual uncovers the trick.
