t is amazing that virtually no school in the world gives its students a Personality Test. Once you take this test you will have a much better understanding of who you are and what your natural tendencies are, and more importantly, you will understand the people who are not like you much more clearly, and uncover a much easier and more effective way to interact and communicate with those people. While no one can be totally defined by which of the four basic groups they fall into, once you learn how to read peoples colors (Red, Blue, Green, Yellow) you will have a competitive advantage in understanding what will be the most effective way to communicate with them.
