When Pablo Picasso, the Spanish artist, was a schoolboy, he was terrible at math because whenever the teacher had him write a number on the chalkboard, he saw something different.
The connection between perspective and creative thinking has to do with habituation and over-familiarization. Over-familiarization with something ( an idea, a procedure, a system ) is a trap. Where creative thinking is concerned, that is the irony of the skill: the more adept you are at something, the less likely you are to look at it in a different way; the greater your skill of a particular discipline, the less you will be tempted to experiment with different approaches. Einstein put it best when he once said, "An expert is a person who has few new ideas; a beginner is a person with many."
