    ladies and gentlemen , good afternoon! i’m very glad to stand here and give you a short speech. today my topic is “youth”. i hope you will like it , and found the importance in your youth so that more cherish it.                                                               
    first i want to ask you some questions:                                                               
    1、do you know what is youth?                                                               
    2、how do you master your 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 divdominance 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 .                                                               
俞敏洪演讲    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, courag                                                               
    can recognize; feel with your body and spirit, and see if you can sense                                                               
    the freshness in the air.                                                               
    yes, yes, yes, it’s a new day, it’s a different day, and it’s a bright                                                               
    day! and most importantly, it is a new beginning for your life, a                                                                                                                                   
    beginning where you are going to make new desicisions, take new actions,                                                               
    make new friends, and take your life to a totally unprecedented level!  in your mind’s eye, you can see clearly the things you want to have,  the paces you intend to go, the relationships you desire to develop, and                                                               
    the positions you aspire to reach.                                                               
    you can hear your laughters of joy and happiness on the day when  everything happens as you dream.                                                               
    you can see the smiles on the people around you when the magic moment  strikes.                                                               
    you can feel your face is getting red, your heart is beating fast, and

    being!                                                               
    you know all this is real as long as you are confident,passionate and                                                               
    you will no longer fear making new sounds, showing new facial  expressions, using your body in new ways,approaching new people, and  asking new questions.
