Akhenaton

Hear the words of prudence, give heed unto her counsels, and store them in thine heart; her maxims are universal, and all the virtues lean upon her; she is the guide and the mistress of human life.

To be satisfied with a little, is the greatest wisdom; and he that increaseth his riches, increaseth his cares; but a contented mind is a hidden treasure, and trouble findeth it not.

The lips of the wise are as the doors of a cabinet; no sooner are they opened, but treasures are poured out before thee.
