Ecclesiastes 2:9-13

⁹So I became great, and advanced beyond all that were before me in Jerusalem: also my wisdom was established to me.

¹⁰And whatever mine eyes desired, I withheld not from them, I withheld not my heart from all my mirth: for my heart rejoiced in all my labour; and this was my portion of all my labour.

¹¹And I looked on all my works which my hands had wrought, and on my labour which I laboured to perform: and, behold, all was vanity and waywardness of spirit, and there is no advantage under the sun.

¹²Then I looked on to see wisdom, and madness, and folly: for who is the man who will follow after counsel, in all things wherein he employs it?

¹³And I saw that wisdom excels folly, as much as light excels darkness.
