"The brain is the most responsive organ of the body. Actually it is the organ that is most susceptible to change and regeneration of all the organs in the body. I have a friend named Gerald Edelman who was a great scholar of brain studies and he says that the analogy of the brain to a computer is pathetic. The brain is actually more like an overgrown garden that is constantly growing and throwing off seeds, regenerating and so on. And he believes that the brain is susceptible, in a way that we are not fully conscious of, to almost every experience of our life and every encounter we have ... We tend to believe that the mind affects the body and the body affects the mind, although we do not generally believe that everything we do affects the brain. I am convinced that if someone was to yell at me from across the street my brain could be affected and my life might be changed. That is why your mother always said, ‘Don’t hang out with those bad kids.’ Mama was right. Thought changes our life and our behaviour. I also believe that drawing works in the same way. I am a great advocate of drawing, not in order to become an illustrator, but because I believe drawing changes the brain in the same way as the search to create the right note changes the brain of a violinist. Drawing also makes you attentive. It makes you pay attention to what you are looking at, which is not so easy."
