The problem with self-centered people is that they tend to not even realize they are self-centered.
It never occurs to them that the world does not revolve around their desires or demands.
They are so blinded by self that they cannot see what others need or want.
When this is brought to their attention, they are quite often baffled or even offended.
It is probably not their fault, however.
Something in their experience most likely made them that way.
Besides, we are all this way to one degree or another.
Usually, we do not notice our self-centeredness until it causes us difficulty or suffering sufficient enough for us to want to change.
This kind of change is extremely challenging, however.
It forces us to look at ourselves in a way that we will not be comfortable with.
We will not like what we see.
If we can get real honest with ourselves, however, we my find that there is more to life than what we think we need or want.
In fact, there is a whole world outside of our needs and wants waiting for us to discover and interact with it.
We get to choose whether we want to look out for ourselves or whether we want to look beyond ourselves, but we probably cannot do both.
