It is only possible to succeed at second-rate pursuits - like becoming a millionaire or a prime minister, winning a war, seducing beautiful women, flying through the stratosphere, or landing on the moon. First-rate pursuits - involving, as they must, trying to understand what life is about and trying to convey that understanding - inevitably result in a sense of failure. A Napoleon, a Churchill, or a Roosevelt can feel himself to be successful, but never a Socrates, a Pascal, or a Blake. Understanding is forever unattainable.
