The feeling center is also image related and having one type preference over another maybe a matter of motivation and how one relates to others.Why don't you think you have a fixation on each of the other feeling types?
Riso-Hudson described a 1 moving back and fourth between the instinctive center and feeling center when acting due to feelings of resentment helping to drive emotions. The thinking center in his words maybe ignored. He does say becoming healthier requires focus on the ignored center, so you maybe on the right track more than you knowSo that would mean I can't have my head fix second and heart fix last (as I think it is now)? Sorry, I don't know that much about enneagram. I didn't think the order mattered.
