Every human being on this earth is born with a tragedy, and it isn't original sin. He's born with the tragedy that he has to grow up. That he has to leave the nest, the security, and go out to do battle. He has to lose everything that is lovely and fight for a new loveliness of his own making, and it's a tragedy. A lot of people don't have the courage to do it.
My mother drew a distinction between achievement and success. She said that 'achievement is the knowledge that you have studied and worked hard and done the best that is in you. Success is being praised by others, and that's nice, too, but not as important or satisfying. Always aim for achievement and forget about success.'
