Ecclesiastes 11:8-9

8but if a man live many years, [and] rejoice in them all, yet let him remember the days of darkness; for they shall be many: all that cometh is vanity.

9Rejoice, young man, in thy youth; and let thy heart cheer thee in the days of thy youth, and walk in the ways of thy heart, and in the sight of thine eyes; but know that for all these [things] 1God will bring thee into judgment.
