“I believe it will have become evident why, for me, adjectives such as happy, contented, blissful, enjoyable, do not seem quite appropriate to any general description of this process I have called the good life, even though the person in this process would experience each one of these at the appropriate times. But adjectives which seem more generally fitting are adjectives such as enriching, exciting, rewarding, challenging, meaningful.
This process of the good life is not, I am convinced, a life for the faint-fainthearted. It involves the stretching and growing of becoming more and more of one's potentialities. It involves the courage to be. It means launching oneself fully into the stream of life. Yet the deeply exciting thing about human beings is that when the individual is inwardly free, he chooses as the good life this process of becoming.”
