Intelligence is the ability to solve problems. For me intelligence is a property of life. Even the most humble unicellular living organism must be intelligent to solve the problems of everyday life. Human intelligence is, for want of a better phrase, a degree of magnitude greater than the intelligence of a Paramecium or, better, of a Chlamydomonas; but the difference is just quantitative and not qualitative.

When you put a prize out there, you legitimise the pursuit of something which is often pretty audacious. Legitimacy also brings about renewed focus and vigour on the problem at hand- it's a little like the context of a 4 minute mile… nobody thought it was possible until it was achieved.

Speaking about the demand side… we have skills and techniques in drug prevention and thousands of advisors have been trained by our programmes around the world to work in the community at school level, especially with children. Children are the most vulnerable group, and we must do our utmost to protect them.

This crisis is expected to trigger migration from these vulnerable regions to the more resilient Northern countries, with projections suggesting 80 million to 200 million people could be displaced by 2050 if we fail to mitigate the impacts.

In football, even though your revenue comes from a source that's linked to your core business, it's not your core business. The core business of any club is simple, to have success on the pitch.

My approach is always to redirect their focus from this nebulous concept of confidence to the concrete tasks at hand. These are tasks they have successfully completed numerous times. Whether they feel confident or not is irrelevant; the real key is maintaining focus in the moment.

The silence I employ has agency behind it. I choose to use it strategically as the pause between stimulus and response, differentiating a considered response from a mere reaction. We need more of this kind of silence.

I learned you always have to use the language of the people you want to convince. If you speak to heads of states and corporations about the costs, that will be incurred to protect the environment, they will never invite you again. If you come and speak their language about job-creation and profit, they will welcome you with open arms.

Making mistakes is necessary- if you don't make mistakes, you can never grow. Every failure is a little lesson in how to be a winner. Failure is an opportunity to learn, to start again, to see problems, and find solutions. Failing may be the reason you win next time!

We must act now, before we reach economic checkmate.

Disruption is treated as an event, and it is a constant and that is the interesting sort of fallacy. As humans we want this state of consistency but if we are taking it as a hypothesis, we are constantly being disrupted, constantly changing and the groundwork we are standing on is shifting all the time.

Life is not a race against other people. Life is a competition with yourself. One of the greatest achievements in life is to outperform yourself and live your greatest life possible. Greatness lives in all of us, but we must all find what it is that ignites our souls.
