Greatness and goodness are not means, but ends.
The TRUTH: It may not lead you to where you thought you were going, but it will always lead you somewhere better. When ignored, it will eventually show itself. The closeness of your relationships is directly proportional to the degree to which you have revealed the truth about yourself. It can be painful.

When the small one is burnt, the big one is done just right!
The early twenties when we drank wood alcohol and every day in every way grew better and better, and there was a first abortive shortening of the skirts, and girls all looked alike in sweater dresses, and people you didn't want to know said Yes, we have no bananas, and it seemed only a question of a few years before the older people would step aside and let the world be run by those who saw things as they were -- and it all seems rosy and romantic to us who were young then, because we will never feel quite so intensely about our surroundings any more.
