According to Sigmund Freud, the ego is part of personality that mediates the demands of the id, the superego and reality. The ego prevents us from acting on our basic urges (created by the id), but also works to achieve a balance with our moral and idealistic standards (created by the superego).
Ego means I in Latin. To an egocentric person, I is the most important word in the language. Great artists and writers are often egocentrics; such people can be hard to live with, though their egocentricity, an unfortunate side effect of their talent, is often forgiven.
