This Ted talk rocks!! Anyone interested in innovation, creativity, and complex decision making will get more out of these 17 minutes than any other I can think of.
The basic message is that if I asked you "what does it feel like to be wrong?" you would think of what it feels like when you REALIZE you're wrong. Not when you are wrong. When you ARE wrong, it actually feels like you are right. Except that there is some fool out there who disagrees with you.
Unless you are always right, please take a few minutes and watch this.
