Bill Gates is a very important person in the computer industry. He has been chief executive officer of Microsoft Corporation for several years. He is also the richest person in the United States. How did he do it?

He learned a lot from his parents. While Bill was going to school, his father went to college, got a degree, and became a successful lawyer. From this, Bill learned that you have to work hard if you want something. His mother was a very busy teacher, but she also enjoyed going to parties. From this, he learned something else: If you want to work hard and play hard, you have to make a schedule.

When Bill was young, he spent a lot of time alone. While most of his friends were playing, Bill read all of the World Book Encyclopedia and finished it when he was 8 years old.

Bill’s childhood was not air work, however. He used to play a lot of sports - swimming, water-skiing, tennis. He was very serious about sports. He loved winning and he hated losing. When Bill got older, he spent more and more time working - and playing - on a computer.

Before he was 20, Bill developed the world’s first computer language for the personal computer. Once when he was thinking about the future, he realized something important. He thought that every home was going to have a computer, and every computer would need software - his software. He said, ‘I’m going to make my first million dollars on software by the time I’m 25.’ And he did!
