ABOUT PERSONALITY TYPES
Becoming self-aware should be the underlying goal of anyone who wants to learn more about their personality Type. Knowing your natural preference allows you to make choices about how you will react to situations and events. You can decide to modify your behavior to create a more favorable outcome. For instance an Introvert might need to turn him or herself up to make an important presentation. You can become more effective by simply knowing who you are to begin with.

Understanding your personality first begins with understanding each of the preference pairs below. They are divided into the following groups:

Source of energy: Do you prefer the outer world or the inner world?

Receiving Information: Do you prefer to use data and information collected, or do you tend to draw your own conclusions and go with your gut?

Making Decisions: Do you tend to see the world in terms of black and white or do you use human emotion to make decisions?

Life Style: When dealing with others do you prefer to have things spelled out or do you prefer to leave things open?
