Truly the light is sweet, and a pleasant thing it is for the eyes to behold the sun: But if a man lives many years, and rejoices in them all; yet let him remember the days of darkness; for they shall be many. All that comes is vanity. Rejoice, O young man, in your youth; and let your heart cheer you in the days of your youth, and walk in the ways of your heart, and in the sight of your eyes: but know that for all these things God will bring you into judgment. Therefore remove sorrow from your heart, and put away evil from your flesh: for childhood and youth are vanity. (Ecclesiastes 11:7-10)
