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.

People at my level [Unilever CEO] shouldn't be motivated by salary. If you paid me double, I'm not going to work twice as much, because I'm already probably maximizing my time available.

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.

Leadership is not just about giving energy ... it's unleashing other people's energy.

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.

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.

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.
