It’s tempting to think of what all you can buy with a billion dollars, but a better question would be if it will affect your personality. The super rich are often thought of as lavish spenders but few have chosen to be humble and show the world that their achievement is not defined by status symbols. Believe it or not, there are still quite a lot of humble millionaires & billionaires out there. Here are a few. Azim Premji The chairman of Wipro Limited often takes a three-wheel auto rickshaw to and from the airport. His net worth is $17.5 billion, still he keeps a tight rein on employees at Wipro headquarters by demanding that staff conserve essentials such as toilet paper and electricity. And apparently he still takes rickshaws to and from the airport.

Chuck Feeney

The co-founder of Duty-Free Shoppers Group donated almost all his fortune.

Having given away most of his wealth, he is only worth about $2 million. He prefers modest restaurants, dresses and lives like an average American, and reportedly does not put on airs. Feeney has said, “I had one idea that never changed in my mind—that you should use your wealth to help people. I try to live a normal life, the way I grew up.”

David Cheriton

The Stanford professor drives a simple 2002 Honda Odyssey.

With a wealth of $3.6 billion, this Stanford professor favors comfort over luxury and has refused to let his wealth change his attitude. He prefers driving around in his 2012 Honda Odyssey and lives in a relatively modest house. He told the Edmonton Journal in a 2006 interview. “These people who build houses with 13 bathrooms and so on, there’s something wrong with them.”
