We often project our 'superhero' aspirations onto our leaders and vulnerability, and other more human traits, are not always encouraged. Organisational leaders often experience loneliness, and the 'truth' within their company is often illusive to them because subordinates will often tell them what they want to hear.

The notion that the Google or Chrome app could become redundant on mobile devices isn't far-fetched. In a future where direct URL visits are less common, the convenience of an all-encompassing app could significantly alter how we interact with our devices.

We have to live in the world as it is, not the world as we wish it would be, is something that we misunderstand. If we are realistic those ideals are usually out of reach, and in fact thinking about them and dreaming about them is a way to punish ourselves for the fact our lives are never going to match up to those ideals.

Every failure has lessons it can give us- and knowing failure is possible and monitoring where you expect it to occur, allows you to divert your attention to the necessary observations and actions to carry out the positive.

In war, you're forced to survive. It's kill or be killed, it's the most basic human instinct. You have to unleash that aggressive shadow side of yourself. It gives you a profound sense of being alive, it becomes a dopamine slot machine.

Taking that first step is your biggest competitive advantage; most people won't do it.

The essence of the evolving global economic system is that all countries are dependent on one another in some way, and this includes finance. Emerging and developing countries are dependent on capital inflows from developed regions. But developed regions are also dependent on funds from the developing world!

This is nothing to do with the 0.000001% who go on to be professional fighters – it's about the 99.9% of people who train because they enjoy it, and connect with it – and who apply the lessons they've learned to deal with the setbacks, failures, victories, challenges and tests they're going to get in work and life.

In my book, the reason I call figures like Stalin, Mao, Pol Pot, etc., red leviathans is that they're actually serving a role that's necessary in a modern progressive revolution: they're the ones who say what is revolutionary and what isn't. Because it turns out that's not an easy question to answer.

There's a considerable correlation between symbols and meaning—especially given how we train modern computer networks these days with unbelievable amounts of data and trillions of parameters. Each parameter is a number representing a probability, but with so many parameters, the answer you get—if you can't follow the vast number of steps—seems unpredictable, much like flipping a coin and not knowing heads or tails. But if you could view all the information, you could determine with certainty which side lands up—that's classical physics. Only in quantum physics does probability acquire a different meaning.

Whenever I write a new song with somebody, it feels like the first time. I sometimes feel embarrassed, humiliated, like I don't know what I'm doing until we find a spark. You have to dare to go to this place where, even though you've done it before, it feels like you don't know what you're looking for until you find it.

We waste 75% of the energy we produce, half the food we produce and half of our natural resources. So much of our waste is waste because people don't understand that it's a resource that can be used!
