A belief or attitude that prioritizes one's own interests and needs above those of others, often seen as excessive self-importance or self-centeredness.

Egoism → It is formed from "ego" (from Latin, meaning I or self) and "-ism" (a suffix used to denote a practice or philosophy). The word "egoism" refers to a philosophy or practice centered around the self or one's own interests.
Think of 'ego' meaning 'self' — that's why egoism is all about focusing on oneself and one's own interests.
