Famous quotes containing the words trail and/or difficulty:
“vanished into nowhere Zen New Jersey leaving a trail of ambiguous
picture postcards of Atlantic City Hall,”
—Allen Ginsberg (b. 1926)
“The great difficulty is first to win a reputation; the next to keep it while you live; and the next to preserve it after you die, when affection and interest are over, and nothing but sterling excellence can preserve your name. Never suffer youth to be an excuse for inadequacy, nor age and fame to be an excuse for indolence.”
—Benjamin Haydon (1786–1846)
