Famous quotes containing the word day:

    Old Day the gardener seemed
    Death himself, or Time, scythe in hand
    by the sundial and freshly-dug
    grave in my book of parables.
    Denise Levertov (b. 1923)

    We swim, day by day, on a river of delusions, and are effectually amused with houses and towns in the air, of which the men about us are dupes. But life is a sincerity.
    Ralph Waldo Emerson (1803–1882)

    The years of imprisonment hardened me.... Perhaps if you have been given a moment to hold back and wait for the next blow, your emotions wouldn’t be blunted as they have been in my case. When it happens every day of your life, when that pain becomes a way of life, I no longer have the emotion of fear. ... there is no longer anything I can fear. There is nothing the government has not done to me. There isn’t any pain I haven’t known.
    Winnie Mandela (b. 1936)
