Famous quotes containing the word heart:

    “People are less self-conscious in the intimacy of family life and during the anxiety of a great sorrow. The dazzling varnish of an extreme politeness is then less in evidence, and the true qualities of the heart regain their proper proportions.”
    —Stendhal [Marie Henri Beyle] (1783–1842)

    “My heart is warm with the friends I make,
    And better friends I’ll not be knowing,
    Yet there isn’t a train I wouldn’t take,
    No matter where it’s going.”
    —Edna St. Vincent Millay (1892–1950)

    “When I was one-and-twenty
    I heard a wise man say,
    “Give crowns and pounds and guineas
    But not your heart away;
    Give pearls away and rubies,
    But keep your fancy free.”
    But I was one-and-twenty,
    No use to talk to me.”
    —A.E. (Alfred Edward)
