I suppose it's knowing when you've come up with an idea that works, when you've got it right, whatever it is.

You can't make decisions if there are no charges or issues to deal with. So it's quite normal to wait until there is some reason to react.

It's not as easy as that... it's disappointing to think that all these countries spend a lot of money trying to get the Olympics.

[Maurizio Arrivabene is quite a character] but only for himself and not for Formula One.

It's the engine. They should have never had that. The biggest mistake people have made... I say, "people," because it wasn't just me alone, was not insisting Mercedes supply Red Bull an engine. Because had they supplied the same engine as they had, you would have seen good racing, you would have seen Red Bull up there last year.

A wise man who was always helpful to me: Mr (Enzo) Ferrari. He always supported me.

I have so much respect for [Bernie Ecclestone] for what he did with this sport. He did so much more than people in tennis or football.
