I am also an introvert as I developed inferiority complex growing up in school. It was hard for me to mingle with my classmates and I preffered to stay alone.
As a professional, I am trying to overcome being introvert although it is quite impossible to become extrovert for me.
I don’t think you need to overcome being an introvert, just learn to live with it and develop skills that will help you do what you want to do! The world needs both introverts and extroverts!!!
