First we fall in love with MBTI. And for some of us it is enlightening and for others, obsessive. But as time goes by and we mature, we start to fall out of love with MBTI and we start to criticise MBTI. And we can be just as obsessive out of love as those who are in love. And the obsessive call to the obsessive.
But eventully the sturm und drang subsides and we are left with a conversation piece.
