Many people assume that they understand what stress truly is. Yet, I believe our collective definition might be somewhat misguided. Hans Selye, often regarded as the pioneer in stress research, characterized it as the body's non-specific response to any demand. Rather than categorizing stress as either good or bad, we should understand it as the body's reaction to any non-specific challenge.

When you engage with highly successful individuals who are open and honest about their journeys, it's invariably surprising to learn how much they attribute their achievements to good luck and favourable circumstances.

The rate of change has become exponential and us as human beings physiologically have not been able to adapt. We just cannot physiologically adapt that quickly – what does it mean for us? This is in some ways Darwinian because he said it wasn't about the strongest that survives, it's those that are most able to adapt.

What we envision is humans using informal reasoning and intuition as a powerful guide, with formal systems then verifying those ideas. In this way, the formal system grounds high-level intuition.

African music more broadly is about rhythm, it's so addictive when you listen to it. People dance from 10 pm to 10 am without really stopping much – it's not complicated harmonies, it's about rhythm and connection. It's like a trance – you get hooked.

Governments need to use their money to develop the future, not recover the past. We have to take this chance, if we don't, we're really going to be in trouble.

Always remember in life there will always be someone that will be in more in need. We could only afford a dime that year, but we gave to help out others!

I am in favour of quotas and targets. I think affirmative action works, and we've had affirmative action in the opposite direction for centuries. So sometimes we have to shock the system. We have to do it to normalise things, to get to a tipping point and then let the system just takes care of itself.

Nuclear weapons continue to be built for basically two reasons: power and prestige. In almost every case where a country has decided to acquire a nuclear weapon they have done it either for power—the power to protect their country from external threats or a desire to project their power in the region.

The average American worker was subject to danger every bit as great as soldiers in war.

I don't believe there's a universal formula for success—I can only share what worked for me, which was driven by enthusiasm for new ideas. What I value most in people is enthusiasm—not passion, which I find overused—but genuine enthusiasm to see opportunities and act upon them.
