Billionaire's Daily $4 Breakfast Secret Revealed.

Despite being worth $106 billion, Warren Buffett is famously frugal and eats a breakfast that costs him less than $4 daily from McDonald's. He also lives in the same five-bedroom house in Omaha, Nebraska, that he bought back in 1958 for $31,500 and uses an iPhone only for phone calls. Buffett believes that his house does the job and couldn't imagine having a better one. He listed his top three investments in life as two wedding rings and his home.
