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.

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

Many think of memory as rote learning, a linear stuffing of the brain with facts, where understanding is irrelevant. When you teach it properly, with imagination and association, understanding becomes a part of it.

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.

No other investment yields as great a return as the investment in education. An educated workforce is the foundation of every community and the future of every economy.

If I have a talent for making some fourth-grader who hates school and reading to hate it a little less, then I have to do the most with what I've been issued.

What if you didn't have education for sports? People with a natural inclination for sports, athletes without any kind of education, without any kind of training, they would just be couch athletes instead of the world class Olympians that we have.

When you think about the children, one of the things that I'm quite concerned about - and I've heard it expressed by others - is trying to find how we can build better accountability, work to provide a level of education that prepares our children for the future.
