    A person may have an idea about himself that will prevent him from doing good work. He may have

the idea that he is not capable (能胜任的) of it. A child may think he is stupid because he does not

understand how to make the most of his mental faculties(机能), or he may accept another person's

mistaken estimate(评价) of his ability. Older people may be handicapped(阻碍) by the mistaken belief

that they are incapable of learning anything new because of their age.

    A person who believes that he is incapable will not make a real effort, because he feels that it would

be useless. He won't go at a job with the confidence necessary for success. He is therefore likely to fail,

and the failure will strengthen his belief in his incompetence. Alfred Adler, a famous doctor, had an

experience which shows this. When he was a small boy he got off to a poor start in arithmetic. His teacher got the idea that he had no ability in arithmetic, and told his parents what she thought in order that they

would not expect too much of him. In this way, they too developed the idea, "Isn't it too bad that Alfred

can't do arithmetic?" He accepted their mistaken estimate of his ability, felt that it was useless to try,and

was very poor at arithmetic, just as they expected.

   One day Adler succeeded in solving a problem which none of the other students had been able to

solve. This gave him confidence. He rejected (refused) the idea that he couldn't do arithmetic and was

determined to show them that he could. His newfound confidence encouraged him to go at arithmetic

problems with a new spirit. He now worked with interest, determination and purpose, and he soon

became extraordinary good at arithmetic.

     This experience made him realize that many people have more ability than they think they have, and

that lack of success is as often the result of lack of knowledge of how to apply one's ability, lack of

confidence, and lack of determination as it is the result of lack of ability.

1. Why might a person be prevented from doing good work? ________.
