Egotism is the drive to maintain and enhance favorable views of oneself, and generally features an inflated opinion of one's personal features and importance. It often includes intellectual, physical, social and other overestimations.
The egotist has an overwhelming sense of the centrality of the 'Me', that is to say of their personal qualities.
