Ecclesiastes 11:8-10

Darby Translation

⁸ but 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.

⁹ Rejoice, 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] God will bring thee into judgment.

¹⁰ Then remove discontent from thy heart, and put away evil from thy flesh; for childhood and youth are vanity.
