Never take your eyes off the cash flow because it's the life blood of business.

You know I think if the people who work for a business are proud of the business they work for, they'll work that much harder, and therefore, I think turning your business into a real force for good is good business sense as well.

I learnt from an early age this need to delegate responsibility out to other team members as there is just too much for one person to do themselves. What is the point of hiring talented team members if you don't give them the freedom to make the most of the chance you have given them?

My number one rule in business, and in life, is to enjoy what you do. Running a business involves long hours and hard decisions; if you don't have the passion to keep you going, your business will more than likely fail. If you don't enjoy what you are doing, then you shouldn't be doing 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.

If you run your business fairly; if you treat people well; if you try to move your business into areas that are making a real positive difference to other peoples lives; I think you'll A. have much pleasant life, but B. I think you'll have a much more successful business.

It's worrying to think more than half the world's population lacks internet access and therefore lacks an equal opportunity to improve their lives.
