Billionaire Warren Buffett is known as one of the richest investors in the world, with a net worth that seems to grow by the day. But the "Oracle of Omaha" wasn't always as filthy rich as he is today.
In fact, 99 percent of his immense wealth was earned after his 50th birthday, reports Business Insider.
That doesn't mean Buffett, 84, was a late bloomer in any sense. He started his financial path toward wealth at a very young age and built his fortune slowly over the years, decade by decade — something we can all do with a little perseverance and a lot of hard work.
Warren Buffett's wealth through the years
Buffett was born in 1930, at the height of the Great Depression, and showed a savvy business acumen as a child. At 11 years old, he was already buying stock: multiple shares of Cities Service Preferred for $38 apiece. When he was just a teenager, he filed his first tax return, delivered newspapers and owned multiple pinball machines placed in various businesses. By the time he graduated high school, Buffett had already bought a 40-acre farm in Omaha, Neb., and sold his pinball machine venture for $1,200.
Legend has it that during his younger years Buffett once said, quite prophetically, that he would be a millionaire by age 30, "and if not, I am going to jump off the tallest building in Omaha."
