It's no secret that Warren Buffett is one of the most successful investors and businesspeople in the world. However, what is not as well known is that he is also one of the happiest.

While Buffett has built remarkable wealth over the decades, his feet are still firmly planted on the ground. He still lives in the same home in Omaha, Nebraska that he purchased in 1958 for $31,500, he has a soft spot for Utz potato sticks and Cherry Coca-Cola, and he still stops by a local strip mall every once in a while to play bridge with his friends.
