Approaches: Humanism - Rogers

The aim of Person Centered Therapy is to remove incongruence feelings.
Incongruence is when your self-image (our current state/how we see ourselves) doesn’t match our ideal-self (our hopes and ambitions/how we want to be).

The practical side to the theory of self states that experiencing incongruence is uncomfortable; therefore each individual seeks to become more congruent. When the distance between the perceived self and the ideal self becomes too great, the person is more likely to experience stress and anxiety.
