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 pays for it with exact change and chooses his meal based on the stock market. He still lives in the same five-bedroom house in Omaha, Nebraska, that he bought back in 1958 for $31,500 and considers it the best house for him. His top three investments in life are two wedding rings and his home. Despite owning roughly 5.5% of Apple, he traded his $20 Samsung flip phone for an iPhone only three years ago, which he uses for phone calls only.
