There are three things to beware of through life: when a man is young, let him beware of his appetites; when he is middle-aged, of his passions; and when old, of covetousness, especially.
ConfuciusFriendship with the upright, with the truthful and with the well informed is beneficial. Friendship with those who flatter, with those who are meek and who compromise with principles, and with those who talk cleverly is harmful.
