I have found the TED talks almost always inspiring, interesting, fascinating, motivating, etc. The speakers are top notch from all walks of life and professions.
I've not found them mentioned in a search of ESMB so I thought I'd start a thread on the topic.
I just listened to and really enjoyed a talk by Jane McGonigal entitled "The game that can give you 10 extra years of life."
On any other day I might have posted something completely different if that's what I'd just watched.
I'm curious if there are any favorite talks that any of you have bookmarked that you'd like to share.
