Some people are much more complex than others.
Originally thought to be an ISFJ. This is wrong because of my lack of experience and she was clearly an INFP Panda type. However, in an earlier part of her life, she had been an INTJ Owl. She still retained this part of her personality.
I have found I can morph-shift but not to me opposite ESFJ and I would have difficulty moving to ESTJ or ESFP, but the move from INTP to INFP would not be that difficult and perhaps even to ENFP for short periods (like public speaking).
