Sorry-existence.

One of the few Freud's theories I agree with involves 3 words I consider vital to human psychology.
Superego.
Ego.
Id.
What are these?
Simple!
Ego is YOU. The actual outcome of your existence. It's what you do, what you say.
Id is the way you take your surrounding.
Superego is what you think, your basic wants and instincts.

Superego and Id combined form the Ego. They are sort of balancing forces.

And in some people, they may "resonate".

Example: pessimistic, gravely formal and perfectionist teacher works his almost entire life in a school that gradually gets better, becoming the elite, the students show (appropriate) high-mindedness.

The teacher starts feeling left behind. Start thinking HIS good ol' school is being swarmed by pretentious pricks who don't know anything, who don't give a shit.

He is not right. It is obvious.
But he has the power to make himself true.
He treats his lamb like a dog, making it a dog being only a matter of time.
He proves himself his right,
Exclude himself from society, that doesn't his most brilliant views on the world (or at least that's what he thinks).

He becomes sick and lonely asocial.

Why?
Wrong neighbourhood, bitch!
