There is something glamorous about being a billionaire. You have the ability to buy and own a big home, a flashy car and anything in between them. There is nothing wrong with that. It is just that there is little to learn from such behavior. Picture this for a moment, a billionaire who does not indulge in buying everything and anything. He or she only buys what he needs. I am talking about the likes of Warren Buffett and like-minded billionaires. What motivates this kind of decisions? Can you apply this to make your life better? Can it help you decide on the best car for you?.
