Do not gain basely; base gain is equal to ruin.
Do not seek evil gains; evil gains are the equivalent of disaster
Happy is the man whom the Muses love: sweet speech flows from his mouth.
He for himself weaves woe who weaves for others woe, and evil counsel on the counselor recoils.
Do not seek dishonest gains: dishonest gains are losses.
Invite your friend to a feast, but leave your enemy alone; and especially invite the one who lives near you.
