Ecclesiastes 4:4-8

I have seen that every [effort in] labor and every skill in work comes from man’s rivalry with his neighbor. This too is vanity (futility, false pride) and chasing after the wind. The fool folds his hands [together] and consumes his own flesh [destroying himself by idleness and apathy]. One hand full of rest and patience is better than two fists full of labor and chasing after the wind. Then I looked again at vanity under the sun [in one of its peculiar forms]. There was a certain man—without a dependent, having neither a child nor a brother, yet there was no end to all his labor. Indeed, his eyes were not satisfied with riches and he never asked, “For whom do I labor and deprive myself of pleasure?” This too is vanity (a wisp of smoke, self-conceit); yes, it is a painful effort and an unhappy task. [Prov 27:20; 1 John 2:16]
