Ecclesiastes 2:10-11

10I did not restrain myself from getting whatever I wanted; I did not deny myself anything that would bring me pleasure. So all my accomplishments gave me joy; this was my reward for all my effort.

11Yet when I reflected on everything I had accomplished and on all the effort that I had expended to accomplish it, I concluded: “All these achievements and possessions are ultimately profitless – like chasing the wind! There is nothing gained from them on earth.”
