    "The only thing holding you back is yourself. Never say never", said a rising 17-year-old singer, Justin

Bieber, who was just an ordinary boy in Canada a few years ago.

    After the accident of falling from the 18th floor and lying in the snow for three hours, my hands were

frozen and my spinal cord (脊髓)was seriously injured. All the doctors and professors in the famous

hospitals in Beijing told me that there was little chance for my hands and my body to recover (康复).

    After half a year of medical treatments and recovering exercises , I could not make any more progress

for over a year . What was worse , I suffered a lot from depression ( 绝望).On top of this , I suffered from insomnia , making every minute of the light seem to last forever. Hopelessly , mom and I came back to my hometown, which is small town in Guangdong.

    At that time , I thought that I would never be able to walk again. I would never love and be loved. I

would never be able to earn even a penny. I would never be able to repay the kindness I got from my

parents and many nice people . Life was meaningless.

    Now two years has passed.My hands are 80% recovered.I can even type faster than a healthy person ! Up to now, I have worked for a law firm as an interpreter for half a year already. Although I don’t earn as much as before, I am able to pay for the food and clothes I need. What’s more , I even have extra money

to buy thanksgiving presents for my parents and my boyfriend. Through my blogs( 博客) , many people

get to know me and like me.I can bring happiness to them. I can help those who are still suffering from

depression and the pain of illnesses by chatting with them….You see, I am living a meaningful life and I

am happier than ever I could have dreamed.

    So, my friends, never say never. As long as you are alive , there is always hope and possibilities. It is

never too late to take action to realize your dreams.
