"It isn't that they can't see the solution. It's that they can't see the problem. They can't see the problem if they are looking in the wrong place. They can't see the problem if they have blinders on - for 'none are so blind as those that will not see'."

I raised you to be a thoroughbred. When thoroughbreds run, they wear blinders to keep their eyes focused straight ahead with no distractions, no other horses. They hear the crowd, but they don’t listen. They just run their own race. That’s what you have to do. Don’t listen to anyone comparing you to me or to anyone else. You just run your own race.
