Before finding fame on "Shark Tank," and before building her New York real-estate empire, Barbara Corcoran was one of 10 kids in a working-class New Jersey family. If nothing else, she learned how to take a risk. She started with a $1,000 loan from her then boyfriend to go into the real-estate business. After a few years they broke up, then the company broke up, and she built her half into the Corcoran Group, a real-estate behemoth that she sold for $66 million in 2001. From there, she landed a spot co-hosting the hit reality TV show “Shark Tank.” Corcoran discusses all this and more in this episode of Business Insider's "Success! How I Did It," including how she stands out in a competitive field.
