Men must sweat to attain virtue.
Man's chiefest treasure is a sparing tongue.
He harms himself who does harm to another, and the evil plan is most harmful to the planner.
Before the gates of excellence the high gods have placed sweat; long is the road thereto and rough and steep at first; but when the heights are reached, then there is ease, though grievously hard in the winning.
Bacteria: The only culture some people have.
Preserve the mean; the opportune moment is best in all things.
