Ecclesiastes 11:9-10

Revised Standard Version

⁹ Rejoice, O young man, in your youth, and let your heart cheer you in the days of your youth; walk in the ways of your heart and the sight of your eyes. But know that for all these things God will bring you into judgment.

¹⁰ Remove vexation from your mind, and put away pain from your body; for youth and the dawn of life are vanity.
