John Paul DeJoria rose from the most humble of beginnings to become one of the richest men in the world. He worked as a newspaper courier at the very young age of nine, and took jobs as a janitor and a tow truck driver just to make ends meet. DeJoria made the smart decision to go into business with Paul Mitchell while he was working for a hair care company. The pair took out a meagre $700 loan, and turned it into a hair care conglomerate with nearly $1 billion dollars in annual sales. DeJoria now also owns Patron Tequila, which sells more than two million cases a year. He has risen from the depths of homelessness to amass a net worth of $4 billion dollars.
