青春 塞缪尔·厄尔曼

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、恢弘的想象、炙热的感情；青春是生命的深泉在涌动。
青春气贯长虹，勇锐盖过怯弱，进取压倒苟安。如此锐气，二十年后生而有之，六旬男子则更多见。年岁有加，并非垂老，理想丢弃，方堕暮年。
岁月悠悠，衰弱只及肌肤；热忱抛却，颓废必致灵魂。忧烦，惶恐，丧失自信，定使心灵扭曲，意气如灰。
无论年届花甲，抑或二八芳龄，心中皆有生命之欢乐，奇迹之诱惑，孩童般天真久盛不衰。人人皆有一台天线，只要你从天上人间接受美好、希望、欢乐、勇气和力量的信号，你就青春永驻，风华常存。
一旦天线倒塌，锐气使冰雪覆盖、玩世不恭、自暴自弃油然而生，即使年方二八，实已垂垂老矣，然则只要竖起天线，捕捉乐观信号，你就有望在八十高龄告别尘寰时仍觉年轻。
Youth Samuel Ullman
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 will, a quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life.

Youth means a temperamental predominance of courage over timidity, of the appetite for adventure over the love of ease. This often exists in a man of 60 more than a boy of 20. Nobody grows old merely by a number of years. We grow old by deserting our ideals.
