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 emotion;
it is the freshness of the deep spring 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动
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.
青春气贯长虹，勇锐盖过怯弱，进取压倒苟安
如此锐气，二十后生而有之，六旬男子则更多见
年岁有加，并非垂老，理想丢弃，方堕暮年
Years may wrinkle the skin, but to give up euthusiasm wrinkles the soul.
Worry, fear, self-distust bows the heart and turns the spring back to dust.
岁月悠悠，衰微只及肌肤; 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
Whether 60 or 10, there is in every human being's heart the lure of wonder, the unfailing childlike appetite of what' 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.
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。
人人心中皆有一台天线，
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，风华长存。
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.
一旦天线下降，锐气便被冰雪覆盖，
玩世不恭、自暴自弃油然而生，
即使年方二十，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。
Thus conscience does make cowards of us all
And thus the naive hue of resolution
Is sicklied o'er with the pale cast of thought
And enterprises of great pith and moment
With this regard their current turns awry
And lose the name of action
这样，重重的顾虑使我们全变成了懦夫
决心的炽热的光彩
被审慎的思维盖上了一层灰色
伟大的事业在这一种考虑之中
也会逆流而退，失去了行动的意义
No matter how wonderful you think, you have to staple on the ground and do the small things everyday.
I have nothing to offer but blood, tears and sweat.

The reason why worry kills more people than work is that more people worry than work.
– Robert Forst
Thomas Jefferson once said,"we should never judge a persident by his age, only by his works."And ever since he told me that, I stopped worrying.(Ronald Reagon)
Expose yourself to your deepest fear; after that, fear has no power, and fear of freedom shrinks and vanishes. You are free. (Jim Morrison)
成长是发生在舒适圈以外的事。
Life is either a daring adventure or nothing.
(Helen keller)
