I spoke at DLD in Munich, Germany, in January.  This was a terrific event, hosted by Burda, a major publishing company. 

John Naisbitt, whom I have admired for many years, closed his keynote with this quote:

"If I had to live my life again, I would have made a rule to read some poetry and listen to some music at least once every week; for perhaps the part of my brain now atrophied would thus have been kept alive through use. The loss of these tastes is a loss of happiness."
-- Charles Darwin, from his autobiography
