Who am I, what is my purpose in coming into this world, and how am I going to spend my life?

Who am I and what is my character? Extroverted, introverted, pessimistic, optimistic.
Who am I, I am the daughter of my parents, the wife of my husband, the mother of my children, the student of a teacher, how many roles have I had in my life?
Who am I? I came to this world to explore, or did I come to this world to play.
oh! Maybe I came to this world to experience the joys and sorrows of life.
Friends, what are you doing in this world?
