Talent is equally distributed, but opportunity is not. Technology is a great equaliser, and an enabler of opportunity. I saw this first hand and through my work now – whether that's investment or philanthropy, that's the work I want to promote.

This is nothing to do with the 0.000001% who go on to be professional fighters – it's about the 99.9% of people who train because they enjoy it, and connect with it – and who apply the lessons they've learned to deal with the setbacks, failures, victories, challenges and tests they're going to get in work and life.

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.

We can win in the struggle to avoid climate chaos, we can win in terms of economic recovery and we can win when it comes to promoting development and justice. All we need is the political will.

Everyone in a high functioning organisation is simultaneously a teacher and a student. They will have been taught by others, and will be teaching others.

I wasn't just fighting for myself. I was fighting for an entire country and millions of fans around the world who believe in me. That is why I will always give 100% in and out of the ring.

For the most part, there are more average celebrities than superstars. When most people think of celebrities, they think of A-listers, but there's also B-list, C-list, D-list, F-list and even Z-list... he gets all the perks of celebrity, without much of the negativity that comes from being an A-lister.

Most of the pain you feel, you create. Most of the pain stems from the conversations we are having with ourselves. It is not the actual event outside of us that affects us. That's the case 99% of the time.

Even just 20 years ago we used to ask the question, 'why do we sleep?' It was one of the last great scientific mysteries; and the crass answer (at that point) was that we slept, to cure sleepiness. Much like saying we eat to cure hunger, however, this tells us nothing of the physiological functions that food and nutrition provide.

I don't believe in a one-size-fits-all approach for talent, you have to approach every individual and opportunity from a bespoke perspective.

I went to collect my prize… it was an American dictionary! Well…when we were looking for a name, I picked up this dictionary and started to flick through. I remember the letter 'R' felt like a good, strong letter and I was flicking through I got to the word R-E-E-B-O-K – a small African gazelle! Well, that felt like us!

Among future technologies that may pose significant existential risks I would rank machine super intelligence at or near the top.
