What is the difference between Egoism and Egotism?

Egoism and egotism are two different words that have similar impressions. According to the Oxford dictionary, Egoism can be defined as the tendency to think selfishly with particular self-interest in mind, while egotism is defined as the tendency to talk excessively about oneself, believing that one is more superior to or essential than others. Egoism can be seen to be a virtue whereby someone thinks or is personally convinced that he is under no compulsion to help others, and him or her also avoids being supported by others.

Egoism is in three forms; ethical Egoism, Psychological Egoism, and rational Egoism. Egotism is a state whereby someone has over-rated himself or herself by the evaluations of his or her skills, look, mental power, significance, humor, and some other esteemed possessed traits or characters. Egotism is characterized by adoring oneself by thinking one is superior, and thinking others are less in the capacity of whatever trait.
