Ecclesiastes 2:10-11 (New International Version)

 ¹⁰ I denied myself nothing my eyes desired;
       I refused my heart no pleasure.
       My heart took delight in all my work,
       and this was the reward for all my labor.

 ¹¹ 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.
