Persona or persona mask can sometimes be helpful or harmful. We may become that role instead of just playing a role. As a result, other aspects of personality do not develop. It is possible that the ego itself, instead of imitating the real nature of the person, imitates the person and deceives himself.

In my opinion, the persona mask shouldn't differ too much from our true self, as it can prevent us from expressing our personality and create frustration, leading to more issues. But I think you can change your personality/identity but not your nature. 🎭
