An elite performer is distinguished not just by skill but by their ability to leverage their mindset to excel during critical moments. This redefines the notion of elite performance to include anyone and everyone. Regardless of the field, role, or domain, anyone can achieve elite status if they consistently deliver outstanding results and rise to the occasion when it's most crucial.

Rationality applies whether you believe in it or not. One idea follows from another – or it doesn't – and if you want some of your beliefs to lead to other beliefs, you have no choice but to be rational. We're committed to it by the very act of discussing, arguing, debating, persuading and convincing.

Many biologists I speak to would say it's almost incomprehensible that something as complex as us has even appeared at all—we might just be very lucky. Or maybe it normally only takes a few hundred million years to go from life to intelligence, and we were just slow. We have a sample size of one.

They described, for example, taste as if it were just electrical signals in the brain, but there's no way such signals alone can produce the sensation of taste. That's the hard problem of consciousness: qualia—the sensations and feelings through which we know the world and ourselves—bear no resemblance to electrical impulses, and physics offers no explanation for how one could give rise to the other.

An example of this successful approach was our first enterprise private 5G launch, which we achieved remarkably fast – from ideation to market-ready delivery in just six weeks. This achievement highlights the effectiveness of our strategy in driving innovation at speed.

I think social media is a great example of this. It feels a little bit like social connection, but I often joke that it's the 'NutraSweet' version—it seems good but doesn't deliver the psychological benefit we expect.

Whether we look at the rioters who converged on the capital, the Gamestop Redditors, Incels or Qanon followers, what they have in common is that they're groups of people who are lonely and craving community. That fundamental need for human connection is missing for significant swathes of our population, and that's dangerous.

Cross-training stands as a key mechanism to balance mastery and specialisation with flexibility and motivation. However, this doesn't mean that you should cross-train every employee in every task. Such an approach would invariably lead to mediocrity.

Jewellery tends to have a much longer life – it can become part of your heritage and have a sentimental value that runs extremely deep, across generations.

When Tiananmen Square happened, tanks were sent in to deal with them. It's not a joke. Do whatever it takes to stay united… People in front of tanks were crushed. The unity of China is more important than those people in Tiananmen Square. Anyone who undermines the constitution shall be put to death

In these political times, that's more difficult, you must plant your flag somewhere, and someone will get upset. You have to be able to take that in your stride.

Another important argument for maintaining the status quo is that eliminating a core symbol of the monetary regime could disrupt common social conventions for using money, possibly in unexpected ways.
