I have ran into several people this past week and I seem to be talking a lot about TED Talks. I have posted several to my website over the past few years. I would encourage everyone to carve out a half-day, get a big cup of coffee and explore TED.com There are so many amazing topics that a half-day will not be nearly enough, but it should get you started.
Here is another one that I found fascinating. I hope you enjoy.
