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.
