The Wings
In addition to the primary Type, each of us has a secondary Type, called a Wing. The Wing is always adjacent to the primary Type. Therefore, if you are a primary Type 7, you could have either a 6 wing or 8 wing. If you are a type 9, you could have an 8 wing or 1 wing, and so on. There are major differences between people of the same Type with a different Wing. The Wing is such a powerful driver that it influences what we want and how we show up more than almost any other factor besides the Type itself. This weighs so heavily on our personality that it even frequently determines whether the Type is introverted or extroverted, and the degree of introversion or extroversion.
