(CareerBuilder.com) -- Many think the only way to succeed is through education. While piling on the degrees can earn you piles of dough -- and debt -- it's not the only option.
Some of today's most successful people don't have a college degree. But what they lack in academic credentials, they make up for in tenacity, brains, guts and strong business sense.
Richard Branson -- In 1970, Richard Branson founded Virgin as a mail order record retailer, and not long afterward he opened a record shop in London. Two years later, the first Virgin artist, Mike Oldfield, recorded "Tubular Bells." Since then many household names, including Ben Harper, Fatboy Slim, Perry Farrell, Gorillaz, Lenny Kravitz, Janet Jackson and The Rolling Stones have helped to make Virgin Music one of the top record companies in the world.
Branson sold the equity of Virgin Music Group -- record labels, music publishing and recording studios -- in 1992 in a $1 billion deal, but he remains chairman of Virgin Group, which today includes Virgin Atlantic, Books, Games, LifeCare, Limousines, Megastores and Hotels.
Barry Diller -- Barry Diller started his career in the mail room of the William Morris Agency after dropping out of UCLA after one semester. He was hired by ABC in 1966 where he created the ABC Movie of the Week, pioneering the concept of the made-for-television movie.
