Because I could never explain anything better than Wikipedia could, here’s an excerpt from it defining the title of this section:
    “The id, ego, and super-ego are a set of three concepts in psychoanalytic theory describing distinct, interacting agents in the psychic apparatus (defined in Sigmund Freud's structural model of the psyche). The three agents are theoretical constructs that describe the activities and interactions of the mental life of a person. In the ego psychology model of the psyche, the id is the set of uncoordinated instinctual desires; the super-ego plays the critical and moralizing role; and the ego is the organized, realistic agent that mediates, between the instinctual desires of the id and the critical super-ego.”

So basically it’s a game of checks and balances with yourself and your thoughts. If that was hard to read, it took me minimum three reads to understand what it was saying.

Ego is the middle, the one that makes compensations and the realistic agent, id is the primal instictive self, and super ego is the critical and moralizing role. Again, we come across the term of “realisitc”. Of course, we understand this as something within reason, according to our environment and our situations, but what I think many fail to realize is that we do not have to equate our ego with our perception on life. 

While ego serves its purpose as a voice of reason and mediation between the two ends of id and super ego, we often allow for that verson of ego to also affect how we judge the world. While things are much easier to observe on an “objective” or rational scale, it leaves little room to relax and enjoy surroundings. If you are always analyzing to understand the construction or existance of things, you never get to really rest. 

It could be argued that letting the mind wander freely and participating in a sort of play would take an equal amount of energy with how your mind jumps from subject to subject, but there’s a difference between running a mile for school and taking a nice walk in the park for a mile isn’t there?

All three images shown are of the same photo of Poly Canyon.The left edited by myself, the right edited by a friend, and the one slapped on top the original, which could be argued as the best looking one.

These three images relate more to (sub/ob)jective arguments, but it is also a good exemplifier of ego being applied to how each individual thinks the world should be viewed.
