Famous quotes containing the words distance and/or resolution:

    “Like a man traveling in foggy weather, those at some distance before him on the road he sees wrapped up in the fog, as well as those behind him, and also the people in the fields on each side, but near him all appears clear, though in truth he is as much in the fog as any of them.”
    —Benjamin Franklin (1706–1790)

    “A resolution to avoid an evil is seldom framed till the evil is so far advanced as to make avoidance impossible.”
    —Thomas Hardy (1840–1928)
