Famous quotes containing the word details:

    “Patience is a most necessary qualification for business; many a man would rather you heard his story than granted his request. One must seem to hear the unreasonable demands of the petulant, unmoved, and the tedious details of the dull, untired. That is the least price that a man must pay for a high station.”
    —Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
