Susan Cain: The power of introverts (TED talk)
But introverts, you being you, you probably have the impulse to guard very carefully what’s inside your own suitcase. And that’s okay. But occasionally, just occasionally, I hope you will open up your suitcases for other people to see, because the world needs you and it needs the things you carry. So I wish you the best of all possible journeys and the courage to speak softly.
