I think consumerism breeds dissatisfaction, and I think that the advertisers play to that. So I cannot be comfortable with that. On the other hand, the cornucopia of products and innovation - I love Apple, for example. That's a temple of consumerism in many ways.

So, you could call me optimistic and hopeful and probably just a little bit naïve, but I'm coming from the space that the best way to predict the future is to get out there and just do it yourself.

What people say often precedes what they think. Some people sometimes say, "I have to hear myself talk before I know what I think." I think language sometimes, because it opens new channels, it opens new doors, is enormously important.

Any prudent business looks at the reality and how to maximize our investment.

I think people often underestimate the power of consumers. But I equally say that consumers are like shock troops: You can't keep them agitated and motivated and committed and active forever. There are pulses where they switch on to a particular issue, and just inevitably they switch off.

I became a vegetarian 55 years ago, and I think it's one of the more important behavioral changes I ever took. The more I see of the beef industry and so on, I believe that to be true.

Companies watch what consumers are doing like a hawk. Just as one letter to a politician can signal an insipient problem, for companies, a trend where people are beginning to switch away from one of their key products to a rival offering on the basis of either claims or real improvements on performance, that's significant.
