I love stirring the pot. I love giving big companies a run for their money - especially if they're offering expensive, poor-quality products.

Our model is to develop each business separately with its own shareholder and management - this way we can concentrate on the job in hand, rather than be part of some enormous and faceless conglomerate.

If you get into business solely to make money, you won’t. If you try to make a real difference, you’ll find success.

And in the process, we have come up with fuels - algae-based fuels, isobutanol-based fuels and other fuels - that we think will power the planes in the future so that, you know, by 2020 I hope that our planes will be powered on fuels that are clean fuels and are not polluting the environment so that we'll have a green airline and an airline that actually has fuels that will be hopefully cheaper than the dirty fuels of the past. So [we're] doing good and also turning a profit at the same time.

Ridiculous yachts and private planes and big limousines won't make people enjoy life more, and it sends out terrible messages to the people who work for them. It would be so much better if that money was spent in Africa - and it's about getting a balance.

Business leaders take things far too seriously, and forget that most of the time people spend in their lives is at work, and it should be fun.

Communicate your passion clearly, concisely and with genuine conviction.
