    The Oracle of Omaha is well-known as perhaps the most successful investor in the world, and he got started early. Warren Buffett bought his first stock at age 11. But he didn't become a billionaire overnight, instead he has been working toward it his whole life, from selling chewing gum as a child to his first post-college job as an investment salesman. Buffett has always held outside investments—his first was purchasing a 40-acre farm while still in high school.

His real estate career started early—during college he worked with his father to revitalize a foreclosed apartment complex in Ohio, and with a $500k investment they managed to turn around its occupancy rate from 34% to 100%. Trump's business interests have expanded over the years to many areas outside of real estate.

    Like Trump, Larry Silverstein was born in NYC and first started working in real estate with his father.

Over the years Silverstein continued grabbing up properties in NYC, and in 2001 he made a successful $3.2B bid for the lease to the World Trade Center.

    Mark Cuban entered the business world at age 12—he turned a profit selling garbage bags so he could afford cool basketball shoes.

He went on to found MicroSolutions, which he sold a few years later for $6M, giving him enough cash to fund his next enterprises.
