This article is a fascinating piece on the art of leadership and how ultimately learnt behaviours inherited from our personal experiences mean that when we reach the top of our tree. However we define it, we seem to have an off switch which shuts down learning and rationalises that if we got to the top, we must be doing it right.  

This perhaps was epitomised by the "Strong and stable leadership" mantra. A 20th century approach to a 21st century challenge which needs all leaders to renew and learn , refine and reflect and above all , never think you have all the answers.
