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.

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.

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. And would it change the way I do things? Not really. So, yes, I am fortunate, and I am ashamed about the amount of money I earn.

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 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.

We put a gender lens on our whole value chain.
