A sensitive man is not happy as President. It is fight, fight, fight all the time. I looked forward to the close of my term as a happy release from care. But I am not sure I wasn’t more unhappy out of office than in. A term in the presidency accustoms a man to great duties. He gets used to handling tremendous enterprises, to organizing forces that may affect at once and directly the welfare of the world. After the long exercise of power, the ordinary affairs of life seem petty and commonplace. An ex-President practicing law or going into business is like a locomotive hauling a delivery wagon. He has lost his sense of proportion. The concerns of other people and even his own affairs seem too small to be worth bothering about.
