Again, I saw vanity under the sun: one person who has no other, either son or brother, yet there is no end to all his toil, and his eyes are never satisfied with riches, so that he never asks, “For whom am I toiling and depriving myself of pleasure?” This also is vanity and an unhappy business.

Two are better than one, because they have a good reward for their toil. For if they fall, one will lift up his fellow. But woe to him who is alone when he falls and has not another to lift him up!
