Yes the OP applies to me very much. I'm constantly on the search for the right words to say. Often that's not possible on my own, so I call on the aid of others to help explain what I'm thinking - hence my bad habit of citing others. So I have the odd paradox of having my own thoughts, but using other peoples' words to explain them to others.
Ahhh paradox....you just can't get more INFJ than that!
