I am learning more and more that being a Four, self means, "I am myself, in relation to...." We do this authentic thing, acting as if we are being are self, and in a sense we are, but at the same time it's very subjective. There is a lot of "I am not just...(fill in the blank), I am (fill in the blank) in relation to."
It finally hit me that I must be a Four because I do this all of the time. I don't just look at my life and think, "I have this and I need it, or I need more." I think, "I (fill in the blank), so and so "fill in the blank." It's quite a pain in the rear. Not an hour goes by that I am not comparing.
