According to Sigmund Freud, the key to a healthy personality is a balance between the Id, the Ego and the Superego.
The Id, the Ego and the Superego are three theoretical constructs, in terms of whose activity and interactions, the mental life can be described and complex human behaviours formed. Hence, these three components of the personality structure are functions of the mind rather than parts of the brain.
