I am a big TED fan. Love the diversity and depth of speakers they gather every year for the annual TED Conference. What's great is they post the talks from the event on their website for all to enjoy.
Do yourself a favor and find a couple of hours of free time.... pop yourself some popcorn, sit down on the couch, and watch some of the talks. I highly recommend Bill Gates most recent presentation, as well as Sir Ken Robinson on creativity, David Merrill on digital blocks, and Benjamin Zander on music and passion.
There are many, many more to take in besides these. Thanks TED for providing such a great medium for learning - for all of us.
