Ecclesiastes 11:4, 8-10

Farmers who wait for perfect weather never plant. If they watch every cloud, they never harvest. When people live to be very old, let them rejoice in every day of life. But let them also remember there will be many dark days. Everything still to come is meaningless. Young people,  it’s wonderful to be young! Enjoy every minute of it. Do everything you want to do; take it all in. But remember that you must give an account to God for everything you do.  So refuse to worry, and keep your body healthy. But remember that youth, with a whole life before you, is meaningless.
