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。
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 enotions;it is the freshess 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.Nobodygrows old merely by a number of years.We grow old by deserting our ideals. Years may 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 or 16,there is in every human being's heart the lure of wonder,the unfailing childlike aooetite for what's 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. 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 sa your aerials are up,to catch waves of optimism,there is hope you may die young at 80.
