Like our physical bodies, our memory becomes out of shape. As children, we are constantly learning new experiences, but by the time we reach our 20s, we start to lead a more sedentary life both mentally and physically. Our lives become routine, and we stop challenging our brains, and our memory starts to suffer.

Mind mapping is a technique based on memory and creativity and comprehension and understanding, so when the student or a child uses the mind map, they are using their brain in the way their brain was designed to be used, and so the mind helps them in all learning and cognitive skills. It simply helps them in what the brain does naturally.

All children are much more intelligent than they are told they are or the school thinks they are; they just have different intelligences.

I'm delighted the world is becoming more mentally literate. A few decades ago, if you mentioned the word 'brain,' no one was interested. Now, nearly every magazine on the planet is featuring the brain. One of my original goals, on one level, was to make myself unnecessary.

I have very talented art directors in my agency who start out telling me, 'Well, this is what the picture is... ' I ask, 'Well, what's the headline?' and they say, 'We haven't done that yet, but it looks this way.' But I'm still writing copy, almost every day.

The most valiant thing you can do as an artist is inspire someone else to be creative.

Art and creativity are crucial, whether you're a mathematician, a scientist, or an artist.

I fell upon Jenny Saville's work and loved these great big pieces she was painting, celebrating all things flesh and woman, and with great big Simone Beauvoir quotations written in mirror writing so you had to look at yourself in the pictures to read them.
