Simon Cowell wasn't always the uber-successful 'American Idol' judge who guided singers to fame and made millions of dollars from his craft. No, when he was younger, the supercilious Brit had lost his record label and was thought of as a joke by his coworkers.

In Britain's The Daily Mail, the 'Idol' guru writes a letter to his struggling, younger self. "It is the early Nineties and you are frustrated, exhausted and worried sick. Life at this moment is not great. Yet just a few years ago, you felt like you were the king of the world!" he begins in his letter.
