    It was raining heavily. I had to wait inside the supermarket like a lot of other people did. A little girl and her mother were waiting, too. The girl looked like 5 or 6 years old. She made me think of my daughter Alice. They are about the same age.

    After a few minutes, the girl got bored and she said to her mom, "Mom, let's run through the rain!"

    "No, dear. We'll wait until it slows down a little." said Mom.

    This young child waited about one more minute and said again, "Mom, let's run through the rain!"

    "We'll get wet if we do," her mom said.

    "No, we won't, Mom. That's not what you said this morning," the young girl said.

    "This morning? When did I say we could run through the rain and not get wet?"

    "Don't you remember? When you were talking to Daddy about his cancer (癌症), you said, 'We have got through (已经熬过) this, and then we will get through anything!'

    All of the people stopped talking. It was a time when innocent trust (纯真的信任) could grow into faith (信心). The mom thought for a minute and said "You are right, sweetheart. Let's run through the rain! If we get wet, maybe we just need washing." Then they ran out.

    They got wet. But some people followed them  ▲  .

    And yes, I did. I ran. I got wet. I needed washing.

    In the ancient Arabic story called Ali Baba and the Forty Thieves, the young hero Ali Baba said "Open Sesame" and a door to hidden treasures was opened to him. The old story had a special meaning for Ma Yun. He drew inspiration from it for Alibaba.com--Chinese largest ecommerce(电子商务) website.

    In 1995, Ma Yun was working for a US trading company when he was introduced to the Internet. "I know nothing about computers and has never touched a keyboard," he said. He searched the word "beer" and nothing came up about Chinese products.

    Ma Yun had an idea. Why not build a large Internet market to connect customers with companies from all over the world? They could do business online in that way. That was how Alibaba began. His company grew quickly. But that didn't mean everything went smoothly. In 2000, many Internet companies failed including Alibaba. But later, he was successful because he managed to attract investment(投资) into his company. "You should stick to your dream," he said. "Everyone thought I was daydreaming when I started. But the most important thing is that we believe in our dream from past to today and tomorrow. Of course we made many mistakes, but we never give up."

    Ma Yun is also smart. For him, success in business is like trying to catch a rabbit. "If there are nine rabbits, focus on catching one--don't try to catch them all," he said. "Change your ways if you need to, but don't change the rabbit. Get one first, put it in your pocket and then catch the others. "

    Thomas Edison was born in 1847. When he was five, his father saw him sitting on some eggs, and asked what he was doing that for. He did not reply(回答). Instead he asked why he was not able to hatch(孵化)chickens while the hens could.

    Edison liked asking a lot of strange questions. His teacher did not understand him and said that he was not bright and was not worth teaching. His mother took him out of school and taught him herself.

    By the time he was ten, he had already built a small chemistry(化学) lab of his own. He planted vegetables in his garden and sold them.

    Once his mother was ill. The doctor said she needed an operation at once. But it was the night and the oil lamp in the room gave off poor light. Edison thought hard and had an idea. He put all the oil lamps he could find on a long table. Then he placed a big mirror(镜子)behind them. The room became quite bright. So the doctor could operate, and his mother was saved. At the age of twelve, Edison began selling candies, sandwiches and newspapers on the train. One day in August, 1862, Edison saw a boy playing on the tracks at a station. A train was coming near quickly, and the boy was too frightened to move. Edison rushed out and carried the boy to safety. The boy's father was the station master. He was so thankful that he taught Edison railway telegraphy(电报通讯术). This gave him a start in his life.

    John was born without arms. As a child, he learned to do many things with his legs. But there were a lot of things he couldn't do. His parents even had to feed him. His seven brothers had to help him to get dressed.

    One day his mom decided not to help John anymore. She told John's brothers not to help him either. "Let John do everything on his own," she said. "If John needs to eat, let him eat by himself. Let him get the dish himself. If he breaks up a few dishes, it's fine. No one will help him to get dressed either. Let him wear his clothes himself. If he can't get dressed himself, then let him run without clothes. But no one is allowed to help him. He has to learn to do everything himself."

    John's mother loved him. She wanted to help him. But if she always helped him, he wouldn't learn anything. She wanted him to be independent.

    Soon John learned to do everything by himself. When he was sixteen, he could even drive a car with his feet. John felt very proud. He thanked his mother for making him independent.

    Today John is a grown-up man. He has a business of his own and he is very successful. He also travels around the world.

    John likes children very much. He likes to talk and play with them. He tells them that they can learn to do anything. He teaches them how to be independent.
