This big bucks self-starter’s credentials include straight D’s in high school and college and 20 jobs by the time she’d turned 23. Don’t believe us?

Now what would you say if we told you it was Barbara Corcoran’s next job that would make her one of the most successful entrepreneurs in the country, when she borrowed $1,000 from her boyfriend and quit her job as a waitress to start a tiny real estate company in New York City?

Daymond John

Here’s a true entrepreneur who keeps us dressed to the nines while we play hard on both field and walk down the path of life. Daymond John’s creative vision helped revolutionize the sportswear industry in the 1990s. As founder, president and chief executive officer of FUBU—“For Us, By Us”—Daymond created distinctive and fashionable sportswear and a host of other related gear. FUBU’s phenomenal success made mainstream apparel companies realize the potential for fashionable sportswear that appeals not just to trendsetting urban youth, but to mainstream teens as well.

Kevin O’Leary

We think this guy is opinionated and ruthless, hungers for big deals and loves to take control—yet he made his millions helping children learn how to read. Kevin O’Leary’s success story starts where most entrepreneurs begin: with a big idea and zero cash. From his basement, he launched SoftKey Software Products. As sales took off, Kevin moved to headquarters in Cambridge, Massachusetts and went on an industry consolidating acquisition binge.
