Repair as well as in the counseling/coaching methods. We have different personalities for different themes of our lives. Some of the personalities tend to work well together, other's not so much. If you've ever wondered why your relationship isn't doing so well, well ONE of the factors to take into consideration is personality. There are instances that couples that are meant to be a train smash - has a harmonious Relationship there are other things to take into consideration as to why they are a success and yours might not be. This personality profiling/quiz is NOT set in stone, this only acts as a guide to better understand why and where the possible conflicts could be coming from. It is my experience that factors like past experiences, stress and trauma changes personality in a negative way and it definitely makes or breaks relationships. To each personality's negative side, there is a positive side. If the Personality is a Positive then they will be a lot more pleasant, but if they are negative and unconscious to their own choices and things always go bad, then their interactions will be negative. Have fun!
