Ecclesiastes 11:7-10

7Light is sweet, and it is pleasing for the eyes to see the sun.

8Indeed, if someone lives many years, let him rejoice in them all, and let him remember the days of darkness, since they will be many. All that comes is futile.

9Rejoice, young person, while you are young, and let your heart be glad in the days of your youth. And walk in the ways of your heart and in the desire of your eyes; but know that for all of these things God will bring you to judgment.

10Remove sorrow from your heart, and put away pain from your flesh, because youth and the prime of life are fleeting.
