Egotism is the tendency to think only about yourself and consider yourself better and more important than other people, and generally features an inflated opinion of one's personal qualities and intellectual, physical, or social importance. Extreme egotism involves little or no concern for others, including those loved or considered as "close," in any other terms except those set by the egotist. It means that you think the world revolves around you (it doesn't), and that you believe you are more important then you really are (you aren't). It is closely related to narcissism, and the possible tendency to speak or write of oneself boastfully and at great length. Egotism may coexist with delusions of one's own importance, at the denial of others. This conceit is a character trait describing a person who acts to gain values in an amount excessively greater than that which he/she gives to others. Egotism is often accomplished by exploiting the altruism, irrationality and ignorance of others, as well as utilizing coercive force and/or fraud.
