It's no secret that swimmer Michael Phelps is an Olympic phenomenon. The winner of (at last count) 25 gold medals, 2 silver, and 2 bronze, Phelps has dominated the Olympics since the 2004 Athens games.

But there's more to Michael Phelps than being one of the greatest athletes of all time. He's also an inspiration to anyone who wants to be the best they can be--in life or on the job--or to regain their mojo after facing extreme adversity (Phelps very publicly dealt with substance abuse issues).
