INTJ Type Development
Like all other INTJs, I developed my Dominant Introverted iNtuition (Ni) as a child and adolescent, often becoming lost in fantasies and being accused of daydreaming.
In my early adulthood, I began to discover the strength of my Auxiliary Extraverted Thinking and quickly found my niche in project management.
In my late 20s and early 30s, my Tertiary Introverted Feeling began to cement my strongly-held personal values, somewhat accelerated by the untimely death of my father at that time.
My late 30s and early 40s saw me exercising my Extraverted Sensing, manifested by an interest in martial arts, massage and dancing.
Now that I’m in my 50s, I’m having fun flexing my other CP “muscles”, especially Extraverted Feeling and Introverted Thinking (with some help from my INFJ wife). I must admit that I still have problems with Extraverted iNtuition and Introverted Sensing, however.

Hi! Your Post “INTJ Type Development” is very interesting for me. Unfortunately my written English is not so good so I write in German: Dir, meinem liebsten, geh

Thank you very much for this information, In fact i think a lot of people are in my position, I have been misdiagnosed as an autistic {high Function Aspergers} due to my social reactions, mind you it was based completely on this fact, I have not had behavior problems, well no more than any other child, But doctors insist that I am. I say let them they don’t have a clue : ) anyway thanks I feel semi normal again or at the very least validated by knowledge I have found to be consistent with the way I am.

Interesting reading. Got to apply this to myself.

One thing you mentioned which struck a chord with me was your mention of daydreaming.
I remember an incident in the 6th grade when my mom wanted to speak with me and said my teacher had called. My teacher said she observed me often staring out the window, seamingly daydreaming and oblivious of the lesson, and she would occasionally have to call my name a couple times to get my attention.
I was pretty much getting straight As so the whole thing never amounted to much.
Reading more about my personality type has certainly enlightened me with respect to many incidents in my past which stuck out in my mind, but for which I hadn’t yet come to strong conclusions.

Very interesting. In the past few years I’ve been developing my extraverted sensing a lot too, with martial arts and meditation and photography. I’m still very much an intuitive type though, for better or for worse.
Could you recommend a good link to more information on these eight modes? I’m not sure what the difference between extraverted and introverted intuition is, for example, and I’d like to learn more about this. Thanks in advance!

Axcho, to learn more about the cognitive processes, I suggest the audio CD, “The 8-Level Model of Psychological Type” which you’ll find on the “Recommended Reading” page: http://www.intj.org/recommended-reading/
