Ecclesiastes 2:10-11

¹⁰And whatever my 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.
