The deepest definition of Youth is, Life as yet untouched by tragedy. And the finest flower of youth is to know the lesson in advance of the experience, undimmed....Youth is distinguished for its whole-hearted absorption in personal enjoyments and personal discomforts. Quick pleasure and quick pain, quick laughter and quick tears, quick absence of care, and quick diffidence, quick courage and quick fear, are conjointly characters of youth. In other words, immediate absorption in its own occupations. On this side, Youth is too chequered to be termed a happy period. It is vivid rather than happy. The memories of youth are better to live through, than is youth itself. For except in extreme cases, memory is apt to count the sunny hours. Youth is not peaceful in any ordinary sense of that term. In youth despair is overwhelming. There is then no tomorrow, no memory of disasters survived.

"The Chinese and the Greeks both achieved certain perfections of civilization—each worthy of admiration. But even perfection will not bear the tedium of indefinite repetition. To sustain a civilization with the intensity of its first ardour requires more than learning. Adventure is essential, namely, the search for new perfections.
There is nothing to be astonished at in this conclusion. Spontaneity, originality of decision, belongs to the essence of each actual occasion [of experience.] It is the supreme expression of individuality: its conformal subjective form is the freedom of enjoyment derived from the enjoyment of freedom. Freshness, zest, and the extra keenness of intensity arise from it. In a personal succession of occasions the upward path towards an ideal of perfection, with the end in sight, gives a thrill keener than any prolonged halt in a stage of attainment with the major variations completely tried out. Thus the wise advice is, Not to rest too completely in any continued real-ization of the same perfection of type."
