Jests that give pains are no jests.
Every man is the son of his own works.
Take my advice and live for a long, long time. Because the maddest thing a man can do is this life is to let himself die.
Be slow of tongue and quick of eye.
It is one thing to praise discipline, and another to submit to it.
Virtue is persecuted by the wicked more than it is loved by the good.
