I cannot imagine being happy anywhere else in the world but in Cape Town - South Africa in general, but Cape Town in particular.

I still enjoy what I'm doing, which is building businesses. I don't play golf. I don't have any particular passion apart from my business and my family, and that gives me all the pleasure that I want.

Any business either grows or dies. You've just got to keep growing.

Money is always the least of the problems. It is finding the right business or growing the right business. You can't do that without the right people.

We should bring in an environmental attitude, and I think luxury should automatically be about sustainability and quality.

I think future engineered species could be the source of food, hopefully a source of energy, environmental remediation and perhaps replacing the petrochemical industry.

China leads the world in energy consumption, carbon emissions, and the release of major air and water pollutants, and the environmental impact is felt both regionally and globally.

I'm in this absolutely gorgeous manor house with acres of quite beautiful countryside. I've got trout in the river, an organic vegetable garden, I've got my work 40 yards from my home. I don't mind being criticised, but where are they criticising from? Which hut are they criticising me from, exactly?
