If you care only about yourself, without a thought for anyone else, you've got a bad case of egocentrism. Egocentrism is a quality of being overly interested in oneself, at the expense of other people.
Egocentrism is an extreme form of selfishness. Psychologists describe it as a state of being unable to see things from anyone's perspective except your own. While egocentrism is considered normal in very young children, it can be a real problem in fully grown adults who think the world revolves around them. If you find yourself convinced that everyone in the room is staring at the tiny blemish on your chin, you can reassure yourself that it's just your egocentrism talking.
