Personality

There are four main personalities that a person has:
-Who others think they are (Perceived External)
-Who they act like they are (Actual External)
-Who they think they are (Perceived Internal)
-Who they really are (Actual Internal)

For the sake of easy communication about these four main personalities that names have been assigned to them.

A main difference between any of these can cause problems.
Consider the following examples:

A difference between Perceived External and Actual External personalities means that the person is misunderstood.

A difference between the External personalities and the Internal personalities means that the person is acting differently than how they normally would act of their own accord; an example of this would be teens acting differently around their peers.

A difference between Perceived Internal and Actual Internal personalities means that the person is out of touch with themselves, and possibly in denial.
