Ecclesiastes 2:10-11

BSB(i) 10 Anything my eyes desired, I did not deny myself. I refused my heart no pleasure. For my heart took delight in all my work, and this was the reward for all my labor. 11 Yet when I considered all the works that my hands had accomplished and what I had toiled to achieve, I found everything to be futile, a pursuit of the wind; there was nothing to be gained under the sun.
