...INTJ enneagram 4...my worst conflicts in life have been with ENFPs --and enneagram 1s and 2s...
I had an ENFP friend and I asked her to tell me how to get to a well-known local spot, driving, of course...she said she had no idea what the directions were, she could just get in the car & "feel" how to get there...we had a hard time maintaining a friendship
I have found that both instruments (MB & Enneagram) are a tremendous help in learining how to get along with people (esp. colleagues) and how to help people from a pastoral care perspective.
Self-knowledge is the key to being authentic. Being authentic is the key to exercising the gifts of the Spirit!
