     Bill is only fifteen years old, but he is already very rich. Two years ago, Bill began a football website

(网站) for young people," I became interested in computers when I was 8 because my father's job is with

computers. As a little boy, I also loved football and so I decided to make a website, especially for people of

my age."

    Bill started the "Football OK!" website two years ago, and now more than 20,000 people visit it every day. 

    Bill is a schoolboy and a businessman as well. He usually gets up at six o'clock and looks at his e-mails.

Then he goes to school from nine to four. In the evenings, he always works for about four hours on his

website.

     Bill's next plan is to set up a new website:" At the moment I an thinking about a new website on American

football, maybe for next year."

     And is Bill the same person that he was three years ago?" No, I am very different now. I have met a lot of

interesting people on the website and I have traveled all over the world." Bill doesn't know about the future."

Maybe I will sell the website. I really don't know. I'll just wait and see.

    When he is 21, Bill will be a millionaire (百万富翁). He always says," Anything is possible"
