Entrepreneur Mark Cuban started with just a few $20 bills in his pocket.
At age 23, he graduated from Indiana University and set off for Texas “with $60, hole in my floorboard, case of oil in the trunk & a floor to sleep on in Dallas,” he tweeted in July.
By age 32, the entrepreneur had already earned his first million: He had sold his first company, MicroSolutions, to CompuServe for $6 million.
Less than 10 years later, he sold his second company, Broadcast.com, to Yahoo for $5.6 billion and became a self-made billionaire.
Cuban has some tips for those looking to build wealth, including what not to do. Don’t pursue any get-rich quick schemes, he wrote on his blog in 2008: “There are no shortcuts. NONE.”
