Ecclesiastes 2:10-11

¹⁰And whatsoever my eyes desired I refused them not; I withheld not my heart from any joy; for my heart was rejoiced with all my toil, and this was my portion of all my toil.

¹¹But when I turned myself to look on all my works that my hands had wrought, and on the toil that I had toiled to accomplish: then, behold, all was vanity and a torture of the spirit, and there was no profit under the sun.
