There's an old adage that the boxer is the last one to know – it's not true, he's the first one to know, but the last to acknowledge it. You can learn from defeat – it's not the end of the world, but you have to learn from it and realise that there are times when you can come back, and times where you have to say, 'enough… enough…. You're getting too hurt… you're just not the guy you were…'

Until about 70,000 years ago, humans were just another kind of animal. They weren't particularly important. Their impact on the world was not greater than that of jellyfish, fireflies, or woodpeckers. However, 70,000 years ago humans evolved new cognitive abilities that turned them into the most powerful force on the planet.

As a collective, we tend to look at progress as being linear, especially where it concerns women's rights. This is a huge mistake and breeds complacency because we risk losing the hard-won gains.

Before I felt leadership was something you earned. Mount Everest, I think changed my opinion quite dramatically. When I came back from that expedition, I realised that all leadership really is, is empowering people to find their purpose, because the only way people are fully engaged and productive and happy is when they are working towards a higher purpose.

We write for the same reason that we walk, talk, climb mountains or swim the oceans- because we can… We have some impulse within us that makes us want to explain ourselves to other human beings… That's why we paint, that's why we dare to love someone- because we have the impulse to explain who we are.

I'm advocating for a right to cognitive liberty, a new international human right that would be the right to self-determination of our brains and mental experiences.

The reason why I fight is that I'm fighting against the pain of seeing my family get sick and fighting against not being able to help them. That's more painful than anything. To see my kids, get sick tomorrow and not being able to help them? That's more painful than anything I would experience in a fight.

These are the kinds of digital services that have been technologically available for 25 years but just haven't been implemented anywhere. Basically, for scalability all you need is more servers.

People underestimate their personal probability of encountering negative …it is not so much that individuals believe that negative events will not happen, but rather that these events are relatively unlikely to happen to them.

A true pet's value lies entirely in its relationship with us, and vice versa. The first fossil evidence of that bond goes back around 30,000 to 40,000 years: dogs buried with humans, including one remarkable case of a dog that had survived two bouts of canine distemper, presumably because its human companion cared for it.

I do believe there's something fundamentally essential about free play—the open-ended combination of elements not confined by a narrow context. This concept is vital not only to humanity but to life itself. Consider Johan Huizinga, the sociologist and anthropologist who, in his book 'Homo Ludens,' famously argued that play is a necessary precondition for culture. I find this perspective accurate.

For me, it wasn't about creating a traditional business plan but rather channelling my 1960s mindset—I aimed to amaze and captivate people. I wanted passersby to wonder, 'Have you seen that? What's going on there?' Ultimately, this desire to make an impression has been the connecting thread in everything I've undertaken.
