The real answer is that there is no complete answer valid for all men, just as Shaw said that the Golden rule valid for all men, just as Shaw said that the Golden Rule is that there is no Golden Rule. The answer which is the valid answer for you is contained within yourself.
And only by living your own life can you find it, living that life of yours after the dictates of your own being and not according to any others, be they gods, heroes, saints or sages or books or theories of any kind. What master do you suppose could teach Shakespeare to be Shakespeare? Or what saint could teach Jesus to be Jesus? And none can teach you to be your own self. Yet Shakespeare learned many things from Lyly and other writers, too. Jesus learned from the masters in the temple, and you may have learned something from this book but that something should not prevent, but indeed encourage, you in self realization to the utmost. And because books can help, let me give a list of some most valuable books for instruction upon the self, humanity in general, and the world of beings and things. Learn from books, however, not for learning’s sake but to live. And from living learn again to have life, fuller, richer and deeper from the experience of it. “Life for your life’s sake” is the life of the blade of grass or the rose. These do not live with reference to bigger and better blades of grass or rarer and more perfumed roses. Their nature is satisfied, and they satisfy Nature, in being themselves and living their own lives according to the laws of their own being. Lets us follow these exemplars and live according to the laws of your own being. So shall we get the real utmost out of our life and ourselves? The grass withers, the flower fades. The man or woman dies. But it is enough that they have lived to their own not another’s utmost, and graced their little hour with their being no more, but no less than themselves.
