4 Carl Jung Theories Explained: Persona, Shadow, Anima/Animus, The Self
In a public situation, we present a different version of ourselves than from the one at home. Every profession has unspoken agreements about which manners are acceptable, and which are not.
It is then the purpose of the persona to suppress the impulses and emotions that are not considered socially acceptable. The difficulty is when one becomes so identified with his persona that he loses all sense of self. The result is an inflated persona with excessive concern for what people think and a lack of courage to endure conflict and refuse others' wishes.
