We have the power of knowledge- for example to save the whales. The whales are obviously not going to save us. We need to have solidarity among humans, that the big problems we are facing, that affect all of humanity and we all equally have the responsibility to do something about it.

The role of science is to educate us about our reality – and we shouldn't be afraid of it. Once we recognise reality, we can adapt to it. If you don't recognise reality, you act irresponsibly, and your actions won't match the environment.

Sometimes it doesn't matter if the other side doesn't care about fairness; provided you do, you explain what's going on. Now it's arbitrary versus arbitrary versus principle versus arbitrary.

We have the tendency to follow those who are comparable to us. It reduces uncertainty and provides us with an extremely effective shortcut into deciding how to best behave in a world that has become overloaded with information and stimulus.

We can see, therefore, that sovereign debt has a systemically important role in the stability of the global economy, the economies of individual states and even the very peace of a country. To be able to then treat this as a market instrument- while appropriate at a time when capital flows were gentile and considered- is clearly not when we can write $2 trillion or more from an entire economy in a matter of seconds.

That's the reason why I tend to say that B2B brand stands for "Boring to Boring" branding. Today, people fundamentally believe that business to business branding has to be incredibly serious… My view is that you should infuse a little bit of emotion into it.

Child labour is one of the worst violations of human rights, it's an affirmation that we don't respect the freedom and dignity of children in our society.

The people in the advanced countries now face a choice: we can express justified horror, or we can seek to understand what may have led to the crimes. If we refuse to do the latter, we will be contributing to the likelihood that much worse lies ahead.

While many investors were caught in this crisis, the leading economists in the world saw it coming.

I fell in love with the process first – they sometimes call it the grind. I fell in love with movement, with training, with everything between the competitions – and falling in love with that was instrumental to me because now, when things don't go right, and I feel vulnerable or emotional, I can dip into that state.

Think of bootstrapping like a multi-stage booster rocket, where each stage propels and prepares you for the next, and the momentum continues building.

Wherever there's judgement there's noise, and more than you think. In the criminal justice system, we saw variability between judges in the severity of their sentencing for equivalent crimes. In business, you may have a company where someone in hiring says, 'bring everyone in, I think they're great' and you end up with a company full of people who shouldn't be there.
