Look, let's just cut to the chase. Let's think about what it means to use Fi. Generally people agree through tests and self examination that they are driven by their values. Then agreeing they are driven by their values they also agree that one of their core values is the inability to be defined. So, I am driven by my values, which define me, me, which can never be defined. It creates an endless circle. Defining what can never be defined, making general what is specific. Just cut to the chase and say "Here is me, this is who I am and how I see it"
I think I am Fi because of Quinlan's brilliant post the other day.
