In Jung's schema, the introvert is the person who derives psychic energy from ideas and values within, the opposite of the extrovert.
Jung believed that each of us tends to depend primarily on a single major psychic function to live in the world.
The influence of the introverted function is markedly less high in North American society, which values action over reflective inwardness than it is in other parts of the world.
Nobody is exclusively introverted; rather, it appears that normal people tend to have a little more or a little less of the introvert quality in themselves.
Therapy is very useful in helping people explore and develop a healthy level of introversion.
