Whether sixty or sixteen, there is in every human being's heart the lure¹ of wonders, 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 wireless² 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.

无论是60岁还是16岁，你需要保持永不衰竭的好奇心、永不熄灭的孩提般求知的渴望和追求事业成功的欢乐与热情。在你我的心底，有一座无线电台，它能在多长时间里接收到人间万物传递来的美好、希望、欢乐、鼓舞和力量的信息，你就会年轻多长时间。

An individual human existence should be like a river—small at first, narrowly contained within its banks, and rushing passionately³ past boulders⁴ and over waterfalls. Gradually the river grows wider, the banks recede⁵, the waters flow more quietly, and in the end, without any visible break, they become merged⁶ in the sea, and painlessly lose their individual being.

人的生命应当像河流，开始是涓涓细流，受两岸的限制而十分狭窄，尔后奔腾咆哮，翻过危岩，飞越瀑布，河面渐渐开阔，河岸也随之向两边隐去，最后水流平缓，森森无际，汇入大海之中，个人就这样毫无痛苦地消失了。

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 sixty more than a boy of twenty.Nobody grows old merely by a number of years.We grow old by deserting our ideals.

青春意味着战胜懦弱的那股大丈夫气概和摈弃安逸的那种冒险精神。往往一个60岁的老者比一个20岁的青年更多一点这种劲头。人老不仅仅是岁月流逝所致，更主要的是不思进取的结果。

Years may wrinkle the skin,but to give up enthusiasm wrinkles the soul. Worry, fear, self-distrust bows the heart and turns the spirit back to dust.

光阴可以在颜面上留下印记，而热情之火的熄灭则在心灵上刻下皱纹。烦恼、恐惧、缺乏自信会扭曲人的灵魂，并将青春化为灰烬。
