"You Can Live Off $500,000 In The Bank And Do Nothing Else" What amount of money would you say it takes for someone to be wealthy or at least comfortable? For some, the number might be in the millions. But Kevin O’Leary, entrepreneur and investor known for his blunt style on Shark Tank, suggests that the amount needed is much less than what most people think. This is especially surprising coming from someone like O’Leary, whose net worth is estimated to be around $400 million. He’s built his wealth through a combination of business ventures, smart investing, and a well-developed personal brand. Yet even with that level of success, O’Leary often emphasizes a surprisingly modest approach to money and financial independence.
