第三章

1."Youth is not a time of life; it is a state of mind. It is not a matter of rosy cheeks, red lips and supple knees. It is a matter of the will, a quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life." (青春不是年华，而是心境；青春不是桃面、丹唇、柔膝，而是深沉的意志，恢宏的想象，炙热的感情；青春是生命的深泉在涌流。)

2."Youth is the season of hope, enterprise, and energy, to a nation as well as an individual." (青春对一个国家和个人来说，都是希望、进取和活力的季节。)

3."Youth is like spring, an over - praised season; if we had as much, say, of the gout in the spring as we have in the fall, we should not so much praise the spring." (青春就像春天，一个被过度赞美的季节；如果我们在春天患的痛风和秋天一样多，我们就不会如此赞美春天了。)

4."In youth we learn; in age we understand." (年轻时我们学习，年老时我们理解。)

5."Youth is a blunder; manhood a struggle; old age a regret." (青年冒失莽撞；成年发奋图强；老年遗憾懊丧。)
