You might know him as the tough, truth-telling investor "Mr. Wonderful" on ABC's Shark Tank, however there's much more than what you see on screen. Entrepreneur, investor, author and television personality Kevin O'Leary got his major business break when he co-founded SoftKey, a tech company that packaged floppy disks and CDs in the 1980s. After buying The Learning Company, a company that created educational and entertainment games in 1995 and absorbing it into SoftKey, O'Leary sold the company to Mattel for more than $3 billion, making him a multimillionaire.

On mindset

"I actually think being an entrepreneur is a state of mind. If you're going to be an entrepreneur, my thesis is that you have to sacrifice everything for some period in your life to be successful.

Entrepreneur

On failure

"I have had some great successes and great failures. I think every entrepreneur has. I try to learn from all of them." -- Kevin O'Leary
