I am an INTJ the last 5 years. In a way I do believe it could be the true me, but... I have also before tested ISTJ and INTP. The variables that change the least are the introversion and thinking. Right now I identify A LOT with being an INTJ but if I look back, the INTP me stands there in the past, pointing a finger at me, laughing. Well not really, but that is how I feel.
