OpenCulture has become a real favourite site for me. Reading about the Dunning-Kruger effect I found another clip with John Cleese. I think everyone can learn from him about creativity. Sometimes we need to be effective and sometimes we need to be creative. This requires different environments. I have never heard anyone calling an office with phones, emails and meeting rooms a creative place. Take an advice from John Cleese and learn to play again.
