I interviewed Kim Kardashian recently and had a conversation with her mother. A lot of people have various thoughts about Kim Kardashian, her mother and her sisters, but it is an incredibly well thought through concept and branding. Each of the daughters appeals to a different segment of the market.

It doesn't make much sense and it's nil premium. They're going to have co-CEOs...which is a very uncomfortable structure.

We do things much the same way as we did 50, 60 or even 70 years ago. The answers may not be wrong, but we haven't experimented to see whether they are or not.

I recently interviewed Bernie Ecclestone in London. He had a go at women, said [Vladimir] Putin should be running Europe and so on. He enjoys it - he's been doing it for such a long time. He has an entrenched position. The truth be known, he is unique, right?

Think through whom you are trying to reach. Tailor what you do and how you do it to appeal to those communities.

I was carrying Jackie Stewart's bag! Formula One was pretty much the same back then.

Somebody who is unique - and this will get me into trouble - by definition cannot be replaced.
