Mark Zuckerberg was born on May 14, 1984. As a little kid, he loved creating little fun computer programs. He set up the network in February of 2004. He was then a second—year student at Harvard University. One day, he had the idea of building a website for Harvard students to get to know each other. He set up the Facebook website. Harvard students could share photos and their personal information there. Soon, the website became very famous. Zuckerberg decided to leave Harvard to run Facebook full time. It was the biggest adventure (冒险) in his life and later brought him great success. Now, the service is popular around the world.
Greetings such as "Have you checked your Facebook page today?" became a part of young people's everyday language in the USA. People can exchange messages and get the latest information about their friends on Facebook. Zuckerberg's dream is to connect people through the Internet. "Facebook is to make the world more open and connected," he said.
What's the young man's secret to success? Zuckerberg believes it's important to have an open mind and be ready to try new things. "The riskiest thing is to take no risks," he once said in an open letter. Sometimes the simplest ideas go furthest. We hope Mark can go much further, maybe even further than Bill Gates.
