Me too, I am really an introverted person, and I have a friend who is an extroverted person. When I go out with him, I feel and realize that he is always more outstanding than me. Moreover, I am quite silenced so I am being more unconfident. But after reading a book called "Quite-the power of introverts in the world that can't stop talking" by Susan Cain, I found my direction again. I put myself in the challenges that I have to be as an extrovert and now I am a soft of bitrovert almost times :))
