Warren Buffett is one of the richest men in the world — a net worth of $84 billion is hard to argue with. He’s an inspiration to business owners, entrepreneurs and people who want to succeed. But how did he become so successful, and what can you learn from it? Buffett, who is regularly heralded as the greatest investor of all time, is still plugging along at 87 years old with a list of accomplishments that began when he was only five. Buffet began his first business operation at that time when he bought and sold Chiclets gum for a profit. At 6, he moved on to packs of Juicy Fruit gum, selling them by the stick and making 2 cents per package. He used the same philosophy with six-packs of Coca-Cola, earning 5 cents for each pack he sold.
