Ecclesiastes 2:9-11

So I became great and excelled more than all who preceded me in Jerusalem. My wisdom also remained with me. Whatever my eyes looked at with desire I did not refuse them. I did not withhold from my heart any pleasure, for my heart was pleased because of all my labor; and this was my reward for all my labor. Then I considered all which my hands had done and labored to do, and behold, all was vanity and chasing after the wind and there was no profit (nothing of lasting value) under the sun. [Matt 16:26]
