ELI5: Explain Like I'm 5

Egotheism

Egotism (or egotheism) is a way of thinking and acting where you always put yourself first. This means that you think only about your wants and needs and don’t worry too much about other people’s feelings or needs. It's different than being selfish because it's taken to an extreme level. It's when you are so focused on your own opinion and feelings that you ignore the opinion and feelings of others around you.
