Ecclesiastes 4:6-8

Better one handful with tranquillity than two handfuls with toil and chasing after the wind. Again I saw something meaningless under the sun: There was a man all alone; he had neither son nor brother. There was no end to his toil, yet his eyes were not content with his wealth. “For whom am I toiling,” he asked, “and why am I depriving myself of enjoyment?” This too is meaningless— a miserable business!
