    “Rejoice, O young man, in thy youth; and let thy heart cheer thee in the days of thy youth, and walk in the ways of thine heart, and in the sight of thine eyes: but know thou, that for all these things God will bring thee into judgment.”
    —Bible: Hebrew Ecclesiastes, 11:9.

    “...to many a mother’s heart has come the disappointment of a loss of power, a limitation of influence when early manhood takes the boy from the home, or when even before that time, in school, or where he touches the great world and begins to be bewildered with its controversies, trade and economics and politics make their imprint even while his lips are dewy with his mother’s kiss.”
    —J. Ellen Foster (1840–1910)

    “Then one will say, ‘He is not dead, maybe,
    Who was mortality’s unshaken lover
    Who loved the spring upon the Tennessee,
    The hushed fall and, again, the coming clover.’
    None will recall, not knowing, the twisted roads
    Where the mind wanders till the heart corrodes.”
    —Allen Tate (1899–1979)
