Despite what preconceived notions you may have of 50 Cent from his music, you can't argue his success. He's been behind multi-platinum selling records, made a smart investment in Vitamin Water (that paid off when it was later purchased by Coca-Cola), and most recently launched his own line of celebrity headphones (SMS headphones). Being successful in one market is tough and doesn't necessarily guarantee success in another. But repeated success, however, is never by accident. I sat down recently with 50 at this year's CES — not just to discuss the latest SMS headphones, but to learn what it takes to be successful, and what encouraged him to recently take up photography.
