Although my spelling is still sometimes poor, I have managed to overcome the worst of my difficulties through training myself to concentrate.

Doing good is good for business.

Give your employees a mission that matches their ambitions. When you challenge people, they surprise you.

We've definitely cracked the technology. Now we're just trying to be able to produce the amount of fuels that we need to satisfy our own needs and then other people's needs.

I have always believed that business should be a force for good.

Happiness doesn't come from making a fortune and owning lots of possessions. 'Stuff' doesn't bring happiness. Family, friends, good health and the satisfaction that comes from making a positive difference are what really matter.

... Our first priority should be the people who work for the companies, then the customers, then the shareholders. Because if the staff are motivated then the customers will be happy, and the shareholders will then benefit through the company's success.
