Pride thyself on what virtue thou hast, and not on thy parentage.
A man is insensible to the relish of prosperity until he has tasted adversity.
Anger that has no limit causes terror, and unseasonable kindness does away with respect. Be not so severe as to cause disgust, nor so lenient as to make people presume.
To tell a falsehood is like the cut of a saber: for though the wound may heal, the scar of it will remain.
The severity of the master is more useful than the indulgence of the father.
It is safer to be silent than to reveal one's secret to any one, and telling him not to mention it.
