Daren Hardy - The Smartest Man in the World

Aristotle said there are four types of people. He who knows not and knows not that he knows not, is a fool. If you want to seek to instruct or guide someone, look at what category they fit into. Daren Daly: Be very careful of those who claim to be so smart. Instead of taking their word for it, just watch them. It's only a matter of time before they arrogantly pick up the back pack and jump out of the plane.
