I don't think our fiduciary duty is to put shareholders first. I say the opposite. What we firmly believe is that if we focus our company on improving the lives of the world's citizens and come up with genuine sustainable solutions, we are more in synch with consumers and society and ultimately this will result in good shareholder returns.

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.

It is unacceptable that more than 1 billion people are hungry every day while another billion are obese.

My biggest fear is that we [Unilever company] at one point in time will not be able to attract the best and brightest [workers]. I don't worry so much about the business, the strategy. If we can continue to attract the best, I know they will ultimately figure out how to run the company in a very tough environment.

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.

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.

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.
