Millionaire Kevin O’Leary is one of the original Sharks on Shark Tank. Known for his abrasive negotiating tactics, he's taken on the sarcastic moniker “Mr. Wonderful” with pride. But when O'Leary talks about his upbringing and the loving family who raised him in Canada, he breaks down in tears. "He'd be really proud of what I've achieved," O'Leary says of his late father, salesman Terry O'Leary.
On the October 21 episode of Shark Tank, while wearing his signature black suit, O’Leary -- the author of the book Cold Hard Truth: On Business, Money & Life -- reveals his rags-to-riches life story. See a sneak peek below. Shark Tank airs Fridays at 9pm on ABC.The BEST SALES on Amazon NOW ]
