Youth Youth is not a time of life,it is a state of mind ; it is not rosy cheeks ,red lips and supple knees,it is a matter of the emotions :it is the freshness ; it is the freshness of the deep springs of life .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.Years 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 .Whether 60 of 16 ,there is in every human being ‘s heart the lure 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’s a wireless station :so long as it receives messages of beauty ,hope ,cheer,courage and power from men and from the infinite,so long as you are young .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.Thank you!青春 青春不是指岁月,而是指心态.粉嫩的脸,红润的唇,矫健的膝并不是青春.青春表现在意志的坚强与懦弱.想象的丰富与苍白、情感的充沛与贫乏等方面.青春是生命深处清泉的喷涌.青春是追求.只有当勇气盖过怯弱、进取压倒苟安之时,青春才存在.果如此,则60见之长者比20岁之少年更具青春活力.仅仅岁月的流逝并不能使他们衰老.而一旦抛弃理想和信念,则垂垂老也.岁月只能使皮肤起皱.而一旦丧失生活的激情,则连灵魂枯老,使人生枯如死水,毫无活力.60岁长者也好,16岁少年也罢,每个人的内心深处都渴望奇迹,都如孩子一般眨着期待的双眼,期待着下一次,期待着生活的情趣,你我灵魂深处都有一座无线电中转站------只有你我年轻,则总能听到希望的呼唤,总能发出喜悦的欢呼,总能传达勇气的讯号,总能表现出青春的活力……… 一旦青春的天线倒下,你的灵魂即为玩世不恭之雪、悲观厌世之冰覆盖；即使你年方20.其实你已垂垂老也.而只要你青春的天线高高耸起,就可以随时接收到乐观的电波-----即使你年过八旬,行将就木,而你却仍然拥有青春,你仍然年轻.
