Ecclesiastes 11:6-9

Sow your seed in the morning, and at evening let your hands not be idle, for you do not know which will succeed, whether this or that, or whether both will do equally well. Light is sweet, and it pleases the eyes to see the sun. However many years anyone may live, let them enjoy them all. But let them remember the days of darkness, for there will be many. Everything to come is meaningless. You who are young, be happy while you are young, and let your heart give you joy in the days of your youth. Follow the ways of your heart and whatever your eyes see, but know that for all these things God will bring you into judgment.
