People find that you don't have to go around managing the maintenance of a building with a tool belt anymore, you can go around with an iPad. You've still got to operate buildings, but our buildings have to be technically oriented as we're challenging them to be greener. So, how do you go from a tool belt to an iPad?

When you look at the numbers, over half the sub-Saharan African population is under 18 years old, versus Latin America, where over half the population is under 25 years old and Asia, where it is under 35 years old. In short, these EM populations are young, expansive and dynamic, not like the stable, more risk-averse populations of the world's developed economies.

I often pose a critical question to businesses: if the economy began transitioning towards sustainability, would this be a boon or a bane for your business? If it's perceived as a threat, your paramount priority should be to modify your business model until this transition becomes an opportunity.

I want to free everyone from that misconception. You can't know everything. And when you shift from a personal attribution for not knowing—thinking, 'I don't know, but everyone else seems to, so I'll fake it or avoid the situation'—to a universal attribution—realizing, 'I don't know, you don't know, nobody knows'—you stand taller. This allows you to embrace what I believe is the most successful mindset: confident uncertainty.

Western civilisation has veered off course; we have de-sacralised the world in which we live. We are collectively insane, and we need to mount our own intervention.

One of the unique aspects of a prize is that when you put a dollar up in a prize purse, you're incentivising teams around the world to spend many times that dollar in pursuit of the competition. You are leveraging dollars in a completely different way- in a philanthropic pursuit.

Doing something that has never been done before is terrifying… all the people who love you will tell you not to do it… not because they're jealous, but because they're genuinely scared for you… they're worried for your wellbeing. If you venture outside that wall, you are really somebody who has traded security and certainty for freedom and risk.

The movements that sustain themselves the best over time are those that have culture at their core, that use art as a means of conveying a message, and use art-making as a means to mobilise a movement.

Without any major adjustments to our conduct and behaviour, we will see the unravelling of an informed civilisation.

All the great achievements of humankind – from building the pyramids to reaching the Moon – are based on large scale cooperation. And all large scale human cooperation is based on belief in fictions such as gods, nations, money and human rights.

We are living in a world where the top 1% of the world's population own more of our planet's wealth than the bottom 95% combined. We live in a world where billions exist in abject poverty without access to the basic food, water, shelter which the rest of us take for granted.

God gave me a talent and I have worked extremely hard to fulfil this talent.
