Have you heard of the story of the four-minute miles? Many years ago, people believed that it was impossible for a human being to run a mile in less than four minutes until Roger Banister proves it wrong in 1954. What happens if you put an animal in a pond? Any animal, big or small, will swim its way through. What happens when people, who do not know how to swim, fall in deep waters? They drown. If an animal who has not learned swimming could escape by swimming, why not you? Because you believe you will drown while the animal does not. Have you ever wondered why the letters are organized in a particular order on your keyboard? You might have thought it is to increase the typing speed. But the fact is that this system was developed to reduce the typing speed at a time when typewriter parts would jam (堵塞) if the operator typed too fast. These three cases show the power of our beliefs. There is no other more powerful directing force in human behavior than belief. Your beliefs have the power to create and to destroy. A belief delivers command to your nervous system. I used a snake in my workshops of children to learn how unrealistic some of their beliefs are. Students of a school in India, said snakes were slippery, slimy(黏糊糊的)  and poisonous. After doing an exercise for changing beliefs, they handled my snake and found it to be dry and clean. They also remembered that only three types of poisonous snakes exist in India. Did this story end the way you thought?
