Millionaire high school dropouts

While the rest of us were negotiating our curfews and cramming to get into university, some of the world's most successful entrepreneurs ditched high school to start building their fortunes. Here are eight.

Jay-Z (Shawn Carter)
This high-school dropout grew up in one of Brooklyn's roughest housing projects, dealing drugs before finding salvation in hip hop. In 1995 Carter took his first single to Def Jam Records, the company he ended up running from 2004 until 2007. In 2008 he signed a 10-year, $150 million deal with Live Nation that gave him control over his records, tours and endorsement deals with companies like Dell and Budweiser.
