Youth is not a time of life, it is a state of mind ; it is not rosy cheeks , red lips and supple knees, it is a matter of the emotions : it is the freshness ; 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.
Years wrinkle the skin , but to give up enthusiasm wrinkles the soul .
中文译文：
青春不是生命的一个阶段,它是一种心态,它不是玫瑰色的脸颊,红色的嘴唇和柔软的膝盖,这是一个重要的情感:它是新鲜的,它是生命的深泉在涌流。
青春是一种气质的勇猛果敢而不是怯懦退缩的食欲,在安逸的冒险。这通常存在于一个60岁的人更可能比一个20岁的男孩。人老不仅仅是岁月的流逝。理想的毁灭,人类才出现了我们变老。
岁月,衰微只及肌肤;热忱抛却,颓废必致灵魂。
