KEN ROBINSON SPEECH

If we think in our own country, I see a big challenge. What we want it to be. We could develop as copy-paste developed country or we could explore another way of being a first world country. I think some people tend to copy european way of life and other the american. What about the latinamerican way of life. Is it possible to take our own creativity and reach to another point of view. I think that in the Bicentennial of our Independence creativity is a good starting point to revisit the theme of what we want to be.
