Kevin O’Leary founded “The Learning Company”, the first software company to apply the principles of consumer goods marketing to the software industry. He sold it to Mattel in 1999 for $4.2 bln. Since then he leads the O’Leary Financial Group, which holds a growing list of businesses.
O’Leary’s lesson: “I’ve learned you need to prepare financially for the unexpected, because there’s a 100% certainty the unexpected will happen. One important way to do this, is to keep 10% of your total assets in cash.”
