Thanks chaos

I have taken the test once or twice. Last time about six months ago IIRC and it gave me one primary type and secondary type.

Off course, it is not like exact science.
In many circumstances I am an introvert, but still do OK with people. Having the choice however, I would prefer to be alone and in a quiet atmosphere.

Sometimes, I relate myself to Bill Gates ( same age ..etc. ) although me & him are a few billion dollars apart LOL. I have noticed that he became president or general manager ( or whatever) of Microsoft for some time when it was necessary, but when the chance came, he left the bigger chair and went back to R&D. Knowing myself, I would have done the same. At my current job, I have declined some managerial positions and remained "in the back room" where I prefer to be.

So my personality type ( INTJ or whatever ) is most comfortable when contact with aggravating people is at the minimum.

I am going to take the test about 5 times with 2 week intervals, so that I have confidence in the results, then maybe I will read/watch a few lectures or seminars about MBTI functions to better analyze those around me.
