If you speak evil, you will soon be worse spoken of.

...Perses, hear me out on justice, and take what I have to say to heart; cease thinking of violence. For the son of Kronos, Zeus, has ordained this law to men: that fishes and wild beasts and winged birds should devour one another, since there is no justice in them; but to mankind he gave justice which proves for the best.

Actions from youth, advice from the middle-aged, prayers from the aged.

Do not get a name as overly lavish or too inhospitable.

And Zeus will destroy this race of mortal men too, when they, at their birth, have grey hair on their temples.

Love those who love you, help those you help you, and give to those who give to you.

Preserve the mean; the opportune moment is best in all things.
