Youth means a temperamental predominance of courage over timidity,of theappetite for adventure over the love of ease.This often exists in a man of sixtymore than a boy of twenty.Nobody grows old merely by a number of years.We growold 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。
