Are people self-centered if they think about themselves all the time? Is it being selfish?

Sigmund Freud, Austrian neurologist and founder of psychoanalysis, introduced the idea of ego as a part of the self that regulates between the wild person that wants everything without delay (the id: libido, envy, desire) and the very restrictive self that says: don’t do anything terrible, you’ll get punished (the super-ego). For Freud, the ego was always trying to make peace between the two other forces.
