Have you ever heard of a girl of 15, who set up a company of her own? Wendy Wong is the girl. She started the business two years ago. She has already written several successful computer games. They are so popular that over half a million games are sold every year. Now all of her family work in her business, and she is still in school.

    She gets up early in the morning and then she talks with her family about the business over breakfast. Every day she goes to school in her own car with a driver, for she is not old enough. She enjoys her school, but some of the work is too easy for her to feel interested. She usually gets “A” grades in all her subjects, so the other students often ask her for help.

    She finished her homework in half an hour after her driver takes her home. After dinner, she goes on her office and goes on working on her computer, writing games until 2 am. She does not usually need so much sleep as other children.
