    After that, we went on down the river. It was very dark that night and it wasn't easy to see where we were going. Suddenly, a big steamboat came at us very fast, and the next minute it was right over us. Jim and I jumped off the raft (木筏) into the water. The boat hit the raft and went on up the river.

    When I came up out of the water, I couldn't see Jim anywhere. I called out his name again and again, but there was no answer. “He's dead!” I thought. Slowly, I swam to the side of the river and got out. I saw that I was near a big old wooden house. Suddenly a lot of very angry dogs jumped out at me. They made a terrible noise and someone called from the house, “Who's there?”

“George Jackson,” I answered quickly. “I've fallen off a river boat.”

    Well, the people who lived in that house were very kind, and they took me in and gave me some new clothes and a good meal. I told them that my family were all dead, so they said I could stay with them as long as I wanted. It was a beautiful house and the food was good there, so I stayed.

    A few days later one of the slaves in the house came to me and said, “Come with me!” Together, we went down to some trees by the river. “In there!” he said and went away.

    On the ground, I found a man, asleep. It was Jim! I was really pleased to see him. When the steamboat hit the raft, Jim told me, the raft didn't break up. Jim swam after it and caught it. Then he began to look for me.

We decided to leave at once. It's all right living in a house for a little while, but you feel more free and easy and comfortable on a raft.

    I did not have a rich father. I tried 3 times for university, but all failed. I applied(申请)for Harvard for 10 times, but all failed. They didn't even want to see me.

    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. "I believe that something, something is waiting for me there, and I have to work hard to prove myself. That was the tough experience. So we gathered 50 thousand US dollars from 18 founders. Little by little, we built up our business. And now, after 16 years, we have a Alibaba group; We have a T-mall group; We have a Taobao group; We have Alipay.

    “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.

George said to the old man, "I am sorry, sir, now all the rooms in the hotel are full, but I have another room left." Then George went to do some cleaning in the room and showed it to the old couple.

    The next day, the old couple wanted to pay for the room. George said, "It is free because it is my own room. I think there may be no rooms in all the hotels in the city. But it was not good to let you out in a heavy rain." The old man said, "You are so kind, and you are the best worker of the hotel." The old couple thanked George and left.

    A few months later, George got a letter with an air ticket to New York and a job offer (工作聘书). When George got to New York, he saw the old man. The old man showed him a large and beautiful hotel and said to George, "This is my hotel. I hope you would take charge of it for me."
