Famous quotes containing the word hard:

    Nothing is hard for lovers, no labor is difficult for those who wish it.
    Jerome (c. 340–420)

    A man’s social and spiritual discipline must answer to his corporeal. He must lean on a friend who has a hard breast, as he would lie on a hard bed. He must drink cold water for his only beverage. So he must not hear sweetened and colored words, but pure and refreshing truths. He must daily bathe in truth cold as spring water, not warmed by the sympathy of friends.
    Henry David Thoreau (1817–1862)

    It is hard for those who have never known persecution,
    And who have never known a Christian,
    To believe these tales of Christian persecution.
    It is hard for those who live near a Bank
    To doubt the security of their money.
    —T.S. (Thomas Stearns)
