A person's self-image is the mental picture, generally of a kind that is quite resistant to change, that depicts not only details that are potentially available to objective investigation by others (height, weight, hair color, gender, I.Q. score, etc.), but also items that have been learned by that person about himself or herself, either from personal experiences or by internalizing the judgments of others. A simple definition of a person's self-image is their answer to the question "What do you believe people think about you?".
Many individuals have a self-image which is excessively high. These kinds of people have exaggerated sense of self worth and also they feel superior to others.

Conversely, many other individuals have a self-image which is excessively low.
