If we achieve our sustainability targets and no one else follows, we will have failed.

The moment you discover in life that it's not about yourself, that it is about investing in others, I think you're entering a steadier state to be a great leader. Because above all, I think the main quality of a leader is to be a human being. There's no reason you are special because you happen to have this job or these responsibilities.

When I interview people, I look at their values. I always say that the best chance of success is if the individual's values are aligned with the corporate values.

If you work at an insurance company that sells premiums you wouldn't even sell to your mother, how happy would you feel to work there? It's going to eat you up. It might last a few years, but it doesn't attract the best people, and it certainly doesn't create the energy and engagement you need to be a long-term performing company.

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.

What is success? I think the most important thing is to achieve what you set out to achieve. Just being a CEO in itself is not success. I would not relate success to a title or a position. My career has had a level of serendipity all along. I've never planned anything out more than a few years.

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.
