Ecclesiastes 2:9-11

[9] So I became great and surpassed all who were before me in Jerusalem; also my wisdom remained with me.
[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.
