"Self"

What is "Self"? What part of yourself is really yourself? What part of my "self" distinguishes me from others?

I am my "Self". Starting from the mind that resides within my body. All my thoughts, emotions, feelings, and opinions lie in my "self". My inner "self" is obviously influenced by the outside world. In reality, i'm not original. I'm a conglomeration of everybody i know, everybody i've read and watched about, and everybody i've observed. I've taken a little part of everybody else, and put them into myself. Nobody is truly original.
In that sense, we really can't separate ourselves from society. What would we be like if we grew completely independent of society? We wouldn't learn a darn thing. Would we even be able to think, considering we wouldn't even know English?
The only part of my "self" which is not influenced by society is how i feel. I always will feel a certain emotion as a reaction to a given situation. This is why communism doesn't work. Communism and the likes can't stop people from feeling. People will always have emotion, regardless of what laws are set, or what is socially correct. We all have emotion.
