I never went into business just to make money - but I found that if I have fun, the money will come. I often ask myself, is my work fun and does it make me happy? I believe that the answer to that is more important than fame or fortune. If it stops being fun, I ask why? If I can't fix it, I stop doing it.

Early on in your career, find someone better than yourself to run the business on a day-to-day basis. Remove yourself, maybe even from the building, and from the nitty-gritty. That way, you're going to be able to see the bigger picture and think of new areas to go into.

We're introducing separate rooms with double beds in all of our planes so people can actually go with their partner and have a proper night's sleep...

There are quite a few things I've done that even I thought might have been one step too far. But if you are willing to make a fool of yourself and make people smile, as long as you do it with a sense of fun, you can get away with it.

So unlike having to convert, you know, all the cars' or all the lorries' petrol stations, once you've actually got the clean fuels, it's relatively easy to, you know, get it to the airplanes.

...making profits is important because it keeps all our people in jobs and, you know, it keeps what we - what we've created going, but, you know, what we're - what I get my - what I'm proud about doing is creating companies which we're really proud of, you know, which we can really be proud of and a byproduct of that hopefully will be that they'll be profitable and be able to pay the bills.

The best way forward is to give more people everywhere greater power to build their own destinies.
