Ecclesiastes 2:9-11

I became greater by far than anyone in Jerusalem before me. In all this my wisdom stayed with me. I denied myself nothing my eyes desired; I refused my heart no pleasure. My heart took delight in all my labor, and this was the reward for all my toil. Yet when I surveyed all that my hands had done and what I had toiled to achieve, everything was meaningless, a chasing after the wind; nothing was gained under the sun.
