Conversely, an unknown but vast number of those grinding out a living today have the potential to be world-changers... if only we could find a way of unlocking that potential. Two ingredients might be enough to do that. Knowledge and inspiration. If you learn of ideas that could transform your life, and you feel the inspiration necessary to act on that knowledge, there's a real chance your life will indeed be transformed. There are many scary things about today's world. But one that is truly thrilling is that the means of spreading both knowledge and inspiration have never been greater. Five years ago, an amazing teacher or professor with the ability to truly catalyze the lives of his or her students could realistically hope to impact maybe 100 people each year. Today that same teacher can have their words spread on video to millions of eager students. There are already numerous examples of powerful talks that have spread virally to massive Internet audiences. - Will Richardson
