I have the ability to make eye contact during a conversation.
^Because...that is a unique ability, as most people fail to make eye contact during a conversation?
Overall, your essay is not that interesting. From what I can infer, you are trying to present yourself as some creature, well a mythical one in your case, that is observant with other humans. K.
Well..
I pay attention to the slightest gestures, their behavior in general. Sincerity is one of the simplest things I am capable of detecting, although most people rather blind themselves to words. I don't hear; I listen. I listen to what they have to say, and if I find it necessary, I comment, but I mostly listen. I am an observer. I enjoy traveling along the other person's mind; evaluating their thoughts. When we express our feelings, the majority of times we are not concise in the way we say them. We tend to diffuse our words, and our real emotions get lost along the way. But I can decipher them; I can observe the true meaning behind words.
^Believe it or not, most people can do this anyway. You are not some unique creature, you are just a regular human being.
but an art I have yet to master is the complete understanding of the human mind.
^Yes, and it will take a very long time to understand the human mind, because there is no definite firm solution. There are theories to help explain certain elements of human thinking.
I do not really know what you are attempting to do with your essay. This is a UChicago essay, and whilst abstract essays are generally interesting, this one isnt, because it just dawns on that one aspect of being an observant mythical creature, when in reality, your essay fails to explain how you are one.
