If wisdom were offered me with this restriction, that I should keep it close and not communicate it, I would refuse the gift.
What you do for an ungrateful man is thrown away.
It is proof of a bad cause when it is applauded by the mob.
Not to feel one's misfortunes is not human, not to bear them is not manly.
Consider an enemy may become a friend.
Accustom yourself to that which you bear ill, and you will bear it well.
