"I became interested in computers when I was 8 years old  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 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 a new website." At the moment I am 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 websites. I really don't know．I'll just wait and see."
