I'd been interested in psychology, different personalities and so on for a long time, but the initial thing that drove me to MBTI was the drive to understand myself and others better. Also I needed some sort of justification for being, well, 'like this'. It had never really satisfied me that I'd gotten strange or rare results from personality tests. It never explained anything of complete personality aka how it manifested in a person's mind, behavior.. I'd always felt that there was something wrong with me and I've been told that many times. Too complex, untraditional, and the thing that I didn't 'work' the way others did. The fact that I couldn't settle for what I supposed to settle for. The drive for understanding, meaning, something more, I wanted justification that that was normal and acceptable. The fact that I can't settle for an okay job, an average place in society and family somewhere in the future and keep repeating what's been repeated for years. That'd kill me. I was always the odd one in the family, the one who thought too much or in a wrong way.
I think the temperament model was what effected me the most and drove towards MBTI. I always longed to be understood.
I still get nagged at a lot at home, partly because I tend to destruy their thought of security with travelling and etc. That place will never change and they're happy like that, but at least I know how to answer to them now.
Rant over and out. I always do get carried away..
