One can also hypnotize himself by uttering certain words. Spoken words can affect itself to do something.
James K Van Fleet, one of the authors of a motivational book in America, recounts his experience, while still serving in the army, one day he saw his battalion commander try to calm himself after drinking drunk at a regiment party at the officers' club.
He saw Colonel Fred.C his battalion commander walked by staggering toward the toilet, worried that he was following the commander to the toilet. When she opened the toilet door she saw that her commander was standing in front of the mirror, her hands on the edge of the washbasin. He saw his reflection in the mirror while talking to his reflection: "Fred .. you are stupid, do not let yourself get drunk !!. You will embarrass yourself, in front of your regiment and commander ... you should not get drunk ... you are not drunk .... stand tall ... control yourself .... do not embarrass yourself! ". So he repeated the word.
Moments later James saw that his commander's situation was beginning to change. He released his hands from the edge of the sink and stood up. Her drunken state began to wane. His eyes look brighter, and his speech is firm. Then he walked back to his shirt with a straight stride and did not stumble like it would go to the toilet.
Many people use techniques like Colonel Fred before going to the pulpit in front of the crowd, facing the boss, or meeting clients.
