Let's call it a supporting evidence to our last lesson about letting your inner child help you. Tim Brown, CEO of Ideo, speaks on the "Serious Play" conference. In 20 Minutes you get with many examples and ideas (and some games) why it is so important to act like a child in certain moments.
BTW: I found this speech at TED, a great site with many interesting speeches. I'm sure to pick the ones that interest "us" most and show them here for you.
