One of the things that Michael Jackson was most known for as an entertainer was making everything he did look easy. Come on, I bet you thought you could moonwalk too until you gave it a try.
Was he blessed with natural ability? No doubt. However, it was his intense drive to be absolutely perfect that allowed him to get up on stage, dance and sing in a way that set him apart from the legions of other talented performers. This is clearly demonstrated in the film "This Is It" in which he makes a mistake during a practice and says matter-of-factly, "This is why we practice." In Michael Jackson's world, there was no room for error, and it was his calling in life to give his audience perfection every time.
The fact is that the cream of the crop of the entertainment world all have one thing in common. They have a work ethic that far exceeds their peers. What does this fact have to do with selling? Everything!
