Ecclesiastes 11:9-10

New Catholic Bible

⁹ Rejoice, young man, while you are young,
    and make the most of the days of your youth.
Follow the inclinations of your heart
    and the desires of your eyes.
Yet remember that for all these things
    God will demand an account.^[a]
10 Banish grief from your heart
    and ignore the sufferings of your body,
    for youth and the prime of life are fleeting.
