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.

    
青春意味著性情的優越，

勇氣驅走怯懦，

冒險戰勝茍安。

二十歲有之，六十歲則更常見。

歲月有加，并非垂老；

理想泯滅，暮年即至。
