furthered Musk's goal of making space travel more affordable and eventually colonizing Mars for humanity's long­term survival. As if this wasn't enough, Musk, 44, is also the founder of Tesla, an electric car company. He has also helped to create three Internet start­ups including the online payment company PayPal. All of them could be said to have turned their industries upside down.

　　The companies Musk started cover three areas: the Internet, sustainable energy and exploring space. Since college, Musk has believed that those areas will most affect the future of humanity and that he should spend his life working on them. "There's no shortage of people with a vision for the future，" Microsoft founder Bill Gates said to Vogue magazine. "What makes Elon special is his ability to make his vision come true."

　　Nothing showed this ability better than the crisis Musk faced in 2008. In 2008, both SpaceX and Tesla were in real danger. SpaceX's three launches had all failed and the company could afford only one more launch. But everything soon turned around. In September 2008, SpaceX launched its fourth rocket and it succeeded. It won a ＄1.6 billion contract with NASA. SpaceX was saved. Musk then shocked the investors and the tech world by pouring his entire personal savings into saving Tesla.

　　Despite his success, Musk's ambition has not gone away. He has also been working on other ambitious projects in recent years.
