Barbara Corcoran's bright-eyed smiles and quick wit come across as vibrant as the pinks and yellows she favors in her wardrobe and home décor. But there is no mistaking this multi-millionaire entrepreneur's no-nonsense approach to business.

Corcoran is widely recognized as one of the 'shark' investors from the popular ABC reality show Shark Tank, but she also has long been known as a real estate mogul in New York City. Her jackpot success came with the sale of her real estate company, The Corcoran Group, for $66 million in 2001.

For this interview with 'Trep Talk, I sat down with Corcoran in her Park Avenue apartment, an appropriately swanky chunk of Manhattan real estate. She shares the humbling moment that taught her an important life lesson, her secret for growing a business, plus pitching mistakes from the shark tank and much more.
