I grew up in the United States. I have learned to cut out the arrogance, sarcasm and bitterness because it is not useful at all ( also slightly unhealthy for your mental wellbeing and in maintaining an accurate view of your abilities). Also, the poster wanted a more objective sample of my experiences, so I decided to tell it as I saw it. There is no point to being arrogant and I have wounded enough people with the actions mentioned above. It might be helpful to know that I have a close family member that is INFJ and she has really helped me to be aware of others and how my actions can really affect them emotionally (she invested a large part of herself trying to get me to acknowledge my weaknesses on the feeling side). Emotions are scary for me as I used to shut them out since I felt that they were of a lesser essence than logic. Even 6 months ago you would have found me to be the typical arrogant, bitter, and sarcastic NTP. I loved to one up people and show where they made no sense. I used this to inflate my ego and self-importance since I felt that everyone else was illogical and lacking in the ability to think for themselves (such as questioning religion, social norms, morality, politics, etc). However, I have learned to tone it down and save it for a select group of friends that can handle the sarcasm and actually enjoy battling over ideas. Hard to say though, I will look up INFJ.
