….says Janan Ganesh in an excellent piece on the leadership skills of Prime Minister David Cameron in yesterday’s FT.The article should be prescribed reading for any leader or leader of leaders to help them understand the difference between good and excellent. He quotes Arsene Wenger, who refers to good players who lack inspiration as “technically clean”. Mr Cameron, Janan Ganesh says “does not engage the viscera” but he is “the best all rounder”. The problem for Mr. Cameron, and every leader, is that being an all rounder is good but not excellent. And we need excellence in our leaders.
