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.

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.

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

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

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.

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.

Many companies are disappointing the citizens of this world by manipulating labor rates, putting horse meat instead of beef out there, or thinking it's totally acceptable to make a T-shirt from a collapsing factory. Increasingly, people don't want to work for these companies, and consumers don't want to buy from them.
