You've probably heard stories of ordinary people performing extraordinary feats-mechanics lifting up cars after a jack falls out; mothers lifting refrigerators after they fall on a child; rescue workers moving large metal beams to help free someone. Most people consider such acts as impossible. However these acts can be done if one is in the proper frame of mind.
Here is a simple game to play with friends who don't read What's Up? Bet your friends that you are ten times stronger than them. If you are a weakling like me your friends will undoubtedly accept. Pass out scraps of paper, about a square inch in size. Ask them to hold it out in front of them for ten minutes. They probably won't be able to hold it out for two. When you pick up a book and hold it out in front of yourself for the full ten minutes, they will be shocked. Here's the trick. The pieces of paper aren't that heavy but your arm is. The reason why people can't hold the paper out for as long is they think about the weight. When you hold up the book (your agenda will work), you need to think about other things. Reading something will work, or you can talk or give a lecture Just do something that can occupy you for ten minutes and don't think about the weight.
That's precisely how people do those other feats of strength. The human body is a lot stronger than most people think, so thinking about it is precisely what must be avoided. Imagine what the human race would b capable of if we didn't limit ourselves by saying, "we can't" when we can.
