Never disregard what your enemies say. They may be severe, they may be prejudiced, they may be determined to see only in one direction, but still in that direction see clearly. They do not speak all the truth, but they generally speak the truth from one point of view; so far as that goes, attend to them.
Benjamin HaydonThe 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
