“The enneagram is a profound, elegant, and compassionate approach to people and their relationships. It describes nine basic world-views and nine different ways of doing business in the world. Each of the nine personality types is something of a pathway through life, with likely obstacles and pitfalls along the way.”
Your principle motivation should be a better understanding of how you work and what will benefit your family, friends, and colleagues. A by-product will be that you will have an understanding of the likely worldview/personality type of your boss, and thus be in a better position to make the relationship work.
