来自 塞缪尔●厄尔曼 的《青春》：
    youth is not a time of life;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 spring 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 be a number of year.We grow old by deserting our ideals.
    Years may wrinkle the skin,but to give up enthusiasm wrinkles the soul.Worry,fear,self-distrust bows the heart and turns the spring back to dust.
    Whether 60 or 16,there is in every human being’s heart the lure of wonder,the unfailing childlike appetite of what’s next and the joy of the game of living.In the center of your heart and my heart there is a wireless station;so long as it receives messages of beauty,hope,cheer,courage and power from men and from the Infinite,so long are you young.
    When the aerials are down,and your spirit is covered with snows of cynicism and the ice of pessimism,then you are grown old,even at 20,but as long as your aerials are up,to catch waves of optimism,there is hope you may die young at 80. [Year grows, but not grows old. ]

下面是译文：
    青春，并非人生旅程中一段时光，也并非粉颊、红唇和体魄的矫健。它是心灵中的一种状态，是头脑中的一个意念，是理性思维中的创造潜力，是情感活动中的一股勃勃朝气，是人生色深处的一缕清新。

    年轻，意味着甘愿放弃温馨浪漫的爱情去闯荡生活，意味着超越羞涩、怯懦和欲望的胆识与气质。而六十岁的老人可能比二十岁的小伙子更多地拥有这种胆识与气质。没有人仅仅因为时光的流逝而变得衰老，只是随着理想的毁灭，人类才出现了老人。
    岁月可以在皮肤上留下皱纹，却无法为灵魂刻上一丝痕迹。忧虑、恐惧、缺乏自信才使人佝偻于时间的尘埃之中。无论是六十岁还是十六岁，每个人都会被未来所吸引，都会对人生竞争中的欢乐怀着孩子般无穷无尽的渴望。

    在你我心灵深处，同样有一个无线电台，只要它不停地从人群中、从无限的时空中接收美好、希望、欢欣、勇气和力量的信息，你我就永远年轻。

     一旦这无线电台坍塌，你的心便会被玩世不恭和悲观失望的寒冰酷雪所覆盖，你便衰老了──即使你只有二十岁。假若这无线电台始终矗立在你的心中，捕捉着每一个乐观向上的电波，你就有希望死于年轻的八十岁。[年龄的增长，但并不衰老]

     说的很好，青春不取决于你的年龄，而是心灵的一种状态，是思维的创造潜力！
     没有思想的人生该多么可怕，忧虑、缺乏自信的人会被尘世所玩弄！
