I mean, at the simplest level, my entire background was in marketing, which largely is about understanding a customer, being able to be intuitive, being able to be empathetic.

Culture is a critical piece of success.

Learning and the exchange of ideas is dramatic.

I personally believe that a critical part to innovation is that exchange of ideas so when you say, 'Here's my idea,' someone else at the next table, who is in a different party, will go, 'Oh, these guys are trying that,' so that comes.

I mean, for all of his faults and the troubles in his marriage, Bill Clinton is still married to a girl he met in the library 25 years ago at school. Can we say that about many of our other leaders today in America, including on the right wing?

I don't think it takes much for a cult to be a cult. Many parts of our society are cultish, and you only need a charismatic leader and some teachings, and before you know it, you have a cult.

Leadership is always about change: it's not about mobilising people to do what they've always done well to continue to do it well.

Making those around you feel invisible is the opposite of leadership.
