Oh Brother, this is what defines Americans, the deluded belief that anyone can become a millionaire/billionaire. People like Kevin are as rare as hens teeth, it's a combination of timing and dumb luck. (he also had financial help from his family)
Kerry Packer, Australia's once richest man (now deceased) said the secret to success is being born to the right family.
There are a lot of multi-millionaires who were not born in the right family...if he meant a rich one.
There is no one secret to success. If success were Rome, then there are many paths to Rome (success).
