Ecclesiastes Chapter 2 Verses 10 & 11

Ecc 2:10 Anything I wanted, I would take. I denied myself no pleasure. I even found great pleasure in hard work, a reward for all my labors. Ecc 2:11 But as I looked at everything I had worked so hard to accomplish, it was all so meaningless—like chasing the wind. There was nothing really worthwhile anywhere.
