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.
青春意味着性情的优越,
勇气驱走怯懦,
冒险战胜苟安。
二十岁有之,六十岁则更常见。
岁月有加,并非垂老;
理想泯灭,暮年即至。
