The reality is that you are looking at your private emails and Facebook and so on at work, and at home you will look at your work emails. We split our private life and work life in a different way than we did in the past. Now, these areas of our lives are totally mixed together.

Before I felt leadership was something you earned. Mount Everest, I think changed my opinion quite dramatically.

We have learned that the things that matter are not the physical, and material things. What matters in life is hope. Tomorrow is not a given, and we must be happy about small things and we must seize the day.

The consumer is far better educated today than he ever was. Consumers don't need to rely on intermediaries to tell them what is good or bad- people are social, they share information with friends and strangers, and go to a broader community for help and assistance.
