Ecclesiastes 11:9-10

Rejoice, young man, in your childhood, and let your heart be pleasant in the days of your young manhood. And walk in the ways of your heart and in the desires of your eyes, but know that God will bring you into judgment for all these things. Therefore, remove sorrow and anger from your heart and put away pain from your body, for childhood and the prime of life are fleeting. [2 Cor 7:1; 2 Tim 2:22]
