Warren Edward Buffett is known as one of the world's leading business magnates. He is an investor and philanthropist too. Considerably, he is one of the most successful investors in the world.

On a new documentary titled "Becoming Warren Buffett," the entrepreneur talks about how he became successful, as reported by Forbes. During a slot on HBO on Monday night, the $73.7 billion net worth, second-richest person in the world, talks about how he is different from the rest of the wealthy moguls.

He talks about his home. Buffett's tastes are not extravagant. He likes to keep things simple which is why he still stays in his five-bedroom Nebraska home. While other business men, like in the movies, decorate their walls with expensive paintings, Warren Buffett pastes newspaper clips on finance in his walls to remind him that anything can happen in the market, as reported by The New Yorker.

When it comes to his car, he does not buy expensive luxury cars. He drives to work in a 2014 Cadillac XTS. He says that GM CEO Mary Barra gave him the idea to buy it after her telling him that there are about 50 things better compared to his previous 8 year old DTS.

And his diet is not made by Michelin chefs. He is known to drink five Coca-colas per day and grabs a McDonald's breakfast when he can. In some days, he thinks about the financial status of the market. If the market is down, he would forego the $3.17 Bacon, Egg and Cheese biscuit and go with the $2.95 Sausage, Egg and Cheese McMuffin instead.

And until now, Warren Buffett is consistently listed as one of the world's most wealthiest people. He is called the "Wizard of Omaha" because of his knowledge in investments and his personal practices when it comes to being frugal despite his wealth.
