My biggest fear is that I become useless or less useful by not being up to date - be it with technology, changing consumers, changing global situations. You continuously have to have a little level of paranoia that forces you to set the bar higher every day.

The last few months have seen a welcome race to the top. Consumers have sent companies a clear signal that they do not want their purchasing habits to drive deforestation and companies are responding. Better still, companies are committing to working in partnership with suppliers, governments and NGOs to strengthen forest governance and economic incentives. It can be done and this Declaration signals a real intention to accelerate action.

My fear is a fear of being obsolete. This is a world that changes very fast, and one of the main human desires is to belong to, to be part of something. It's probably one of our greatest needs next to oxygen.

The very essence of capitalism is under threat as business is now seen as a personal wealth accumulator. We have to bring this world back to sanity and put the greater good ahead of self-interest. We need to fight very hard to create an environment out there that is more long term focussed and move away from short termism.

This world is changing enormously. In any position in a company you need to work very hard on learning new skills every day, but you also need to unlearn some of the old skills from the past.

I don't have any frustrations. It sounds a little silly, but life is too short for me. I don't worry about all the things that happen, I just think about what to do with them. I work a lot with blind people in my spare time and I count my blessings every day.

Imagine all the food mankind has produced over the past 8,000 years. Now consider that we need to produce that same amount again — but in just the next 40 years if we are to feed our growing and hungry world.
