ECCLESIASTES 2:10-11

¹⁰And whatsoever mine eyes desired I kept not from them: I withheld not my heart from any joy, for my heart rejoiced because of all my labour; and this was my portion from all my labour.

¹¹Then I looked on all the works that my hands had wrought, and on the labour that I had laboured to do: and, behold, all was vanity and a striving after wind, and there was no profit under the sun.
