Creativity and imagination begin with perception. Neuroscientists have come to realize that how you perceive something isn’t simply a product of what your eyes and ears transmit to your brain. It’s a product of your brain itself. And iconoclasts, a class of people I define as those who do something that others say can’t be done — think Walt Disney, Steve Jobs, or Florence Nightingale — see things differently. Literally. Some iconoclasts are born that way, but we all can learn how to see things not for what they are, but for what they might be.
