A sparing tongue is the greatest treasure among men.
Invite your friend to dinner; have nothing to do with your enemy.
Gain not base gains; base gains are the same as losses.
Badness you can get easily, in quantity. The road is smooth and lies close by. But in front of excellence the immortal gods have put sweat, and long and steep is the way to do it, and rough at first. But when you come to the top, then it is easy, even though it is hard.
When you deal with your brother, be pleasant, but get a witness.
There is also an evil report; light, indeed, and easy to raise, but difficult to carry, and still more difficult to get rid of.
