Ecclesiastes 2:10-11 RSV

10 And whatever my eyes desired I did not keep from them; I kept my heart from no pleasure, for my heart found pleasure in all my toil, and this was my reward for all my toil.
11 Then I considered all that my hands had done and the toil I had spent in doing it, and behold, all was vanity and a striving after wind, and there was nothing to be gained under the sun.
