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.

Many of us grow up thinking of mistakes as bad, viewing errors as evidence of fundamental incapacity. This negative thinking pattern can create a self-fulfilling prophecy, which undermines the learning process. To maximize our learning it is essential to ask: "How can we get the most from every mistake we make?"

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 used to take formal notes in lines of blue, and underline the key words in red, and I realised I needed only the key words and the idea.

They called me the best, when I knew I wasn't, and they called him the worst, when he was the best. I mean, there could be no more antipodal environment. So I began to question: What is intelligence? Who says? Who says you're smart? Who says you're not smart? And what do they mean by that?
