Ecclesiastes 6:7

⁵ The child, though neither seeing the sun nor knowing anything, has more rest than that man,

⁶ even if he lives a thousand years twice over but fails to enjoy his prosperity. Do not all go to the same place?

All a man’s labor is for his mouth, yet his appetite is never satisfied.

⁸ What advantage, then, has the wise man over the fool? What gain comes to the poor man who knows how to conduct himself before others?

⁹ Better what the eye can see than the wandering of desire. This too is futile and a pursuit of the wind.

Do read the surrounding verses too, because the context often says more than a single verse.
