     Today, no one thinks of Bill Gates as a failed entrepreneur or a college dropout yet. Both of these

things are true of Gates, American richest man and the pioneering genius who leads the computer

software industry.

     Gates was born in Seattle in 1955. Young Gates' grades weren't always great. Although he did well in

science and maths, he was something of an underachiever. But in the eighth grade he found his passion. In

the 1960's, the mothers' club at Gates' school bought a computer for the students.

     Gates discovered it and soon became computer crazy. He spent every evening and weekend trying to master computer technology. His computer usage fees were so high that he hide from his parents the

amount he spent. It wasn't long, though until his programming passion turned toward real goals. He and

his friend Paul Allen started a company called Traf-0-Data. Their goal was to use new computer

technology to count passing cars. The company went broke. After all he was only in the eighth grade.

And it didn't discourage his interest in technology. In fact, it was because of his passion for programming

that he later dropped out of Harvard. He spent two dissatisfying years at the university before he left to

form another company with Allen. Gates and Allen called their software company Microsoft. In the

1970s it was only a small operation running out of loaned office in Arizona. Gates would work late into

the night and sometimes sleep under his desk. Today, Microsoft is the software industry giant. As

chairman and chief executive officer of Microsoft, Gates operates as the prince of programmers.

     Despite his wealth and recent marriage, Gates hasn't slowed down. He is still a workaholic, putting in

long hours at the office.
