Ecclesiastes 11:9-10

⁹Have joy, O young man, while you are young; and let your heart be glad in the days of your strength, and go in the ways of your heart, and in the desire of your eyes; but be certain that for all these things God will be your judge.

¹⁰So put away trouble from your heart, and sorrow from your flesh; because the early years and the best years are to no purpose.
