INFJ counselor

I hadn't given much attention to the "Myers-Briggs Type Indicator" tests until I took one and discovered that I am (supposedly) an "INFJ counselor." I am not quite sure what that is supposed to mean. However, I confess that on reading descriptions of the "type" I felt much that resonated with me, and rather powerfully at that.

My problem is that I am by nature a wary beast. I distrust ideas that are complete unto themselves, and so are easily digested, for fear they might be poison.

And so I wonder if the real underlying principle is not that we come in predefined types, and know so from our innate resonations, but rather that the human brain is built to find things with which to powerfully resound.
