     Sixteen years ago, a boy gave me an important gift. It was a smile.

      It was the early autumn of my first year at a middle school, and my old school was far away. As a result, no one knew who I was. I was very lonely, and afraid to make friends with anyone.

     Every time I heard the other students talking and laughing, I felt my heart break. I couldn't talk with anyone about my problems.

Then one day, my classmates were talking happily with their friends, but I was sitting at my desk unhappily as usual.  At that moment, a boy entered the classroom. I didn't know who he was. He passed me and then turned back. He looked at me, with a smile.

    Suddenly, I felt the touch of something bright and friendly. It made me feel happy and warm. That smile changed my life. I started to talk with other students and made friends. Day by day, I became closer to everyone in my class. The boy with the lucky smile has become my best friend now.

    One day I asked him why he had smiled, but he couldn't remember doing so!

     It doesn't matter because all the dark days have gone. I believe that the world is what you think it is. If you think it is lonely, you might always be alone. So smile at the world and it will smile back.

    A lot of people said Alibaba was a terrible model. As I said, "I believe it. I think this thing could be big. I never thought it would be so big like today.

    “You are so smart, how could you make a company like that? People asked. Bill Gates, Warren Buffet, the Jack Welch, Larry Page, Mark Zuckerberg, the difference between those people and other people, they are always optimistic(乐观的)for the future. They never complain. They always try to solve the problems of the others. When you are optimistic, it's always an opportunity (机会).“Jack, Where's the opportunity? I don't have a job. I don't have this. I don't have that.” We are at the best of time of this century. The best asset(财产)you have is that you are young. Don't complain. Let the other people complain. The opportunity lies, always lies where people complain. I saw a lot of people, especially young people have fantastic ideas every evening. But the next morning, they go to the office on time again.

    Tomorrow is new. Make the move. Make action. Whether investors(投资者)believe this or not, whether your friends believe it or not, whether your parents believe it or not, that's not important. You believe it. Your team believe it and work day and night on this. Everything happens. Make enough mistakes. You fall, and you stand up. Any mistake is an income and a wonderful revenue(收益). Don't worry about the money. Money follows the people. Young people should follow the dreams. If you have a dream, just to go ahead.

    Once upon a time, there was a tree which wanted to become a treasure box. One day, a farmer cut it down and sold it to a carpenter(木匠). The tree was happy because he thought the carpenter would make it into a treasure box.

    To its surprise, the carpenter made it into a feed box for animals. The tree felt very disappointed because that was not its dream. Several years later, the feed box was thrown away. Someone picked it up and placed it into an old temple. The tree forgot its dream little by little.

    One day, a couple came to the temple. The woman gave birth to a baby boy. There wasn't a bed in the temple. So they placed the baby in the feed box. They loved him and regarded him as their treasure. The tree suddenly realized that it became a real "treasure box" at that time.

    Sometimes you may think your dream will not come true. Don't forget your dream. It may be realized in another new way.
