Ecclesiastes 6:7-9

All the labor of man is for his mouth [for self-preservation and enjoyment], and yet the desire [of his soul] is not satisfied. [Prov 16:26] For what advantage has the wise man over the fool [for being worldly-wise is not the secret to happiness]? What advantage has the poor man who has learned how to walk [publicly] among the living [with men’s eyes on him; for being poor is not the secret to happiness either]? What the eyes see [enjoying what is available] is better than [craving] what the soul desires. This too is futility and chasing after the wind.
