The following story illustrates how this power works:
Allan applied for a new job, but he didn't believe he will get it, since his self-esteem was low, and he considered himself as a failure and unworthy of success.
He had a negative attitude toward himself, and therefore, believed that the other applicants were better and more qualified than him.
Allan's mind was occupied with negative thoughts and fears concerning the job, for the whole week preceding the job interview. He actually, anticipated failure.
On the day of the interview, he got up late, and to his horror he discovered that the shirt he planned to wear was dirty, and the other one needed ironing. As it was already too late, he went out wearing a wrinkled shirt and without eating breakfast.
During the interview, he was tense, negative, hungry and worried about his shirt. All this, distracted his mind and made it difficult for him to focus on the interview. His overall behavior made a bad impression, and consequently, he materialized his fear and did not get the job.
Jim applied for the same job too, but approached the matter in a different way. He was sure that he was going to get the job. During the week preceding the interview, he often visualized himself making a good impression and getting the job.
In the evening before the interview, he prepared the clothes he was going to wear, and went to sleep a little earlier. On day of the interview, he woke up earlier than usual, and had ample time to eat breakfast, and then to arrive to the interview before the scheduled time.
Jim made a good impression and got the job.
What do we learn from these two stories? Was there any magic used? No, everything happened in a natural way.
