Ecclesiastes 2:9-11

Yes, I was great, greater than anyone else who had ever lived in Jerusalem, and my wisdom never failed me. Anything I wanted, I got. I did not deny myself any pleasure. I was proud of everything I had worked for, and all this was my reward. Then I thought about all that I had done and how hard I had worked doing it, and I realized that it didn't mean a thing. It was like chasing the wind — of no use at all.
