A couple weeks ago I mention the book Quiet: The power of introverts by Susan Cain. This is about a 15-minute presentation of the key points of the book in a brilliant TedTalks video.
“Speak softly” — Susan Cain

I am a big fan of Ted and listen to many presentations each week. I personally thought this was the worst one I had ever watched. However, I read the book first and loved it. I think she makes some very valid arguments on the topic.
