The youngest billionaire, Mark Zuckerberg, co-founder of Facebook social network, and his girlfriend Priscilla Chan rent a house with a monthly payment in Palo Alto, CA near the headquarter of the famous company. Zuckerberg house was built in 2002, has an area of 353 square meters (3800 square feet), 5 bedrooms and 4 bathrooms. Clearly, Zuckerberg can afford to build or buy the most expensive luxurious house, what really seemed to stem the move, is the location. Now, Zuckerberg lives only a few steps away from Facebook Headquarters. This surely comes in handy since he reportedly spends as much as 16 hours a day at the office and comes home only to sleep.

Mark clearly does not want to change the neighborhood and prefers to live as close as possible to his "working nest", as he previously also rented a house in the same area. His previous house was smaller- only 183.5 square meters (1.976 square feet), also had 4 bathrooms, but the number of bedrooms were only 3, and besides it was much further- seven blocks away from workplace.

The young billionaire even allowed Oprah's (57-year-old American billionaire actress best known for her talk show "The Oprah Winfrey Show", the World's Most Powerful Celebrity on Forbes' 2010 celebrity list and the Most Influential Person in Show Business in 2009.) camera crew inside his home for an exclusive look at his modest dwelling place and office.

However, not only Zuckerberg surprises everyone with his quirks. For example, David Packard, the billionaire and co-founder of Hewlett-Packard lived and died at his 139 square meters (1,500 square feet) home also near Palo Alto. Another well-known IT-mogul Sergey Brin, Google co-founder and one of the richest people in the world, until 2006 lived in a simple three-room apartment, until he married ...

That is how live people, who are fully devoted to the job they love. Thus, they are creative, gifted and happy in their own way.
