The secret to Happiness: Ancient wisdom Here again, I saw emptiness under the sun: a lonely man without a friend, without a son or brother, toiling endlessly yet never satisfied with his wealth. Two are better than one; they receive a good reward for their toil, because, if one falls, the other can help his companion up again; but alas for the man who falls with no partner to help him up. (Eccles. 4:7-10).
