The human athlete has a special trick that no other animal has. It is called self-talk. Athletes talk to themselves to warm up, to focus and to help themselves believe they will win. A few simple words like “I can do it!” and “It is now or never!” can make the difference between winning gold or not.

Self-talk is also used by speakers, actors and other performers. Before a speech, politicians believe that their words will win votes. And, self-talk helps students stay calm even when stumped by hard exam questions. Self-talk is a life skill you can use wherever you are, whenever you need it.

The whole idea of talking to themselves seems strange to many people. Imagine your teacher saying, “For homework, talk to yourself for half an hour tonight.” You might think he is playing a joke on your class. Instead, adults teach kids all about talking to other people. There are many books on why, when, what and how to communicate with the rest of the world. Thus, you can grow up knowing a lot more about people around you than about yourself.

It is good to speak and listen to others. But there is great value in making time to listen to yourself. When you do, you get to know yourself better. Along the way, you may discover the power you have for using words well.

Such ideas are so exciting to psychologists that they have been trying to learn more about self-talk. In the study, people found certain lost items at home more easily when they talked to themselves while searching for the things.
