Ecclesiastes 11:6-10

6 In the morning sow your seed, and at evening 1withhold not your hand, for you do not know which will prosper, this or that, or whether both alike will be good.
7 Light is sweet, and it is pleasant for the eyes to 2see the sun.
8 So if a person lives many years, let him rejoice in them all; but let him remember 3that the days of darkness will be many. All that comes is 4vanity.
9 5Rejoice, O young man, in your youth, and let your heart cheer you in the days of your youth. 6Walk in the ways of your heart and 7the sight of your eyes. But know that for all these things 8God will bring you into judgment.
10 Remove vexation from your heart, and 9put away paina from your body, for youth and the dawn of life are vanity.
