Despite his success, Daymond John is still hungry.
Financial constraints and the desire for success give entrepreneurs an advantage in starting a business, the founder of FUBU and "Shark Tank" co-star said. It's the concept behind his most recent book, "The Power of Broke." But it's not a concept that applies only to financially disadvantaged people.
"The people that use 'the power of broke' ... most are the people that get to a level of success and realize they still have to maintain that hunger, that drive, that focus," he said.
