I think that TED talks are amazing! The concept of "Ideas Worth Speading," is so true. Currently there are over 1,400 talks about a variety of topics from classroom teaching, to sciences, to motivational speakers.
Simon Sinek spoke at TIES 2012. He is the author of "Start With Why: How Great Leaders Inspire Everyone to Take Action." He was SO great, but his TED talk about leadership was even greater!! Over 9 million people have watched it - take a peek:)!!
