Sorry to say most of us are struggling to answer this question when someone approaches asking if we know who we truly are or who you really are. I believe the lack of knowing yourself is one of the major problems ⚠️
You can understand the needs that prompt a person to ask such existential questions, but how do you expect him to identify himself, according to you. To know who you are means to study who you are, and this, in my opinion, is not easy for ordinary people and small-minded people.
This question is existential and has been asked by mankind since the beginnings of history, and philosophy has tried to provide approaches to thinking about the subject, but it has never succeeded in providing complete answers about who we really are and what is the purpose of our existence.
