 Throughout one of the most storied careers in pop music history, British singer-songwriter Rod Stewart has sold more than 120 million albums worldwide, officially making him one of the best-selling musical artists ever. But guess what? He's still willing to get his hands dirty to this day. Not bad for a kid who left school at the age of 15 only to wind up becoming a gravedigger. And sure, back then, Rod might have had higher ambitions of becoming a professional football player, but I'm confident he's more than happy with how things turned out. After releasing his first solo album in 1969, Stewart's 1971 album Every Picture Tells a Story would catapult him to a super stardom.
