10 Surprising Facts About Bill GatesThere are a lot of things about one of the wealthiest men in the U.S. that you probably didn't know.

1. As a young teenager at Lakeside Prep School, Gates wrote his first computer program on a General Electric computer.

It was a version of tic-tac-toe, where you could play against the computer.

2. Once his school realized Gates' proclivities for coding, they let him write the school's computer program for scheduling students in classes.

3. Like many other successful tech entrepreneurs, Gates was a college dropout.

He left Harvard University in 1975 to fully devote himself to Microsoft.

4. Gates was once arrested in New Mexico, in 1977.

He was driving without a license and ran a red light.

5. He used to fly coach until 1997.

Now, he has his own plane. He calls that his "big splurge."

He acquired the codex at a 1994 auction for $30.8 million.

That, he says, is his biggest regret in life thus far.

9. He used to memorize the license plates of his employees at Microsoft.

Gates wasn't exactly a chill boss. Back in the day, he had a fanatical work ethic that he expected his employees to replicate by working all the time. "I knew everybody's license plates so I could look out in the parking lot and see when did people come in [and] when were they leaving," he told the BBC.
