Carl Jung

The human being is an amphibian who lives on the land of reality and in the sea of fantasy.

The more you are able to say 'this is I,' the more you are able to be yourself.

One cannot be too careful in the choice of one's enemies.

The man who promises everything is sure to fulfill nothing, and everyone who promises too much is in danger of using evil means for the attainment of his ends.

The highest, most decisive experience is to be alone with alone. To experience oneself as a single, individual being is the core of individuation.
