I studied the Mbti, Carl Jung invention. However, don't even try tests, quiz. Or what so ever. Please, observe for others or me. Ah, i know alot about the cognitive functions. Enneagrams, alot so! Classic Jungians, Variants. And, alot of lit course of a fire level of knowledge! But be wise, sometimes this might go wrong. Just like having the wrong cookie?! Also, please tell me about yourself. Please ensure that you are enjoying and using this for fun. Maybe, for others? Okay, bye!
