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 in all my labour: and this was my portion of 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 vexation of spirit, and there was no profit under the sun.
