Creativity and Innovation

I came across this video while I was watching another video and it really was rather interesting how Edward De Bono used hats for his analogies on creativity and innovation. What he said makes a lot of sense and I also believe that people can sometimes sabotage creativity, especially if you're working in a group and you have someone who always looks at the glass as being half empty. It's hard to be creative when there's negativity, but there are ways to get around that as he has stated.
