Have you seen the inspiring commercial that Michael Jordan did for Nike? It's the one where he talks about all of his mistakes, such as the free throws and game-deciding shots that he's missed over the years. 

I love that commercial for its right attitude about failure, but I'm even more impressed with it after seeing a follow-up interview with Jordan.

A reporter asked Michael Jordan if the statistics that he quoted in the commercial were correct. Jordan's response? "I don't know."

Now that answer surprised me at first, until I realized its significance: Michael Jordan is so unconcerned with failure that he truly has no idea how many shots he's missed in his career or how many games have been lost because of his mistakes. He simply took the word of the statisticians at Nike for those numbers
