Egoism:

Egoism is concerned with the role of the self, or ego, as the motivation and goal of one’s actions. Different theories are generally categorized into either descriptive forms (describing that people do act in self-interest) or normative forms (prescribing that they should). Other egoism definitions emphasize action according to one’s will rather than self-interest — seen by some in the psychiatric community as a truer sense of egoism. Egoism: Egoism is a philosophical concept positing that self-interest is the ultimate guide to all actions and behaviors. Can manifest as extreme self-centeredness, where one prioritizes their own needs, but doesn’t necessarily involve boasting. Used to describe a philosophical stance or ethical theory about the role of self-interest in morality and motivation.
