The billionaire you are most like is Mark Cuban.

Mark Cuban is a high-profile investor and owner of the Dallas Mavericks. He is also a reality TV star on the show Shark Tank.

Like Mark, you are a dynamic, high-energy individual driven to succeed. Raised with middle class values, you have a strong work ethic and expect everyone to work as hard as you do, which can cause you to be a bit unforgiving at times. Fancy schools and hand-outs or not for you. It is possible that others may view your self-confidence as arrogance, but you don't care.
