We are scientifically naked in front of this threat. We do not have the diagnostics to quickly detect an MDR or XDR case. Once detected, we do not have the drugs to effectively treat the patient at reasonable cost, and we do not have a TB vaccine.

Many people say that if you're the brightest person in the room, you're in the wrong room – that's totally right. You need to bring in people with much more expertise than you to take the business forward. I started out making shoes by hand – I'm a shoemaker, not an intellectual.

Creativity is about solving interesting problems, and problems are interesting because they have constraints. You cannot think outside the box, but you can think along the edges of the box. The box is something to lever and learn against. Look for the edges of the box and don't deny the boundaries!

Our philosophy has been about trying to control the entire customer experience. A lot of people, when they think about branding, they think about advertising and marketing. But we actually don't do any advertising or marketing. Instead, we invest all of that money into the customer experience, and then our customers do our marketing for us through word of mouth.

We are very porous now, and it isn't just through neurotechnology, it is through all modes of technology that are designed to interpret and change our cognitive and effective functioning. So as I wrote this book, it is more of a call to recognise that in the modern era we have to expand our notion of liberty to include the right to cognitive liberty.

A great entrepreneur always acts with full intention and without limitation, always striving for the best in everything they do. From an early age I knew I had to rely on myself, look after myself, to not be afraid of anything. It gave me huge confidence and unshakable belief.

The world is changing now faster than you and I change our socks! It's constantly changing, and that constantly changing world is going to induce more movie-making. If you go on YouTube, you can see the most talented young people all over the world who take a camera and start to film ideas they have and put them online.

We have the tendency to follow those who are comparable to us. It reduces uncertainty and provides us with an extremely effective shortcut into deciding how to best behave in a world that has become overloaded with information and stimulus. We need shortcuts!

The moment you send Billy Connolly, Lenny Henry and Victoria Wood out somewhere to make an appeal – they are representatives of 'normal people' perhaps in some ways more than pop stars.... Comedians are a kind of humdrum kind of celebrity, and as such I think they're very good at evoking empathy.

The potential for blockchain is to accelerate the digitization of financial markets. Blockchain gets everyone excited as it has the potential to convene these different parties together to reach the necessary agreements, in that sense it is a unique enabler, a coordination mechanism. That has massive implications on the structure of our financial markets.

As a matter of history it's crucial to distinguish between what I have taken to call 'mercantile capitalism' and what I like to call 'modern capitalism'. Mercantile capitalism I think of as prevailing in Britain, Holland, Spain and elsewhere from around 1500 to 1800 or so.

I'm genuinely convinced that the upcoming decade will be the era of India as a product nation. The product revolution has begun, what we're terming as 'India SaaS' – the development of global SaaS products originating in India, not merely for the Indian market, but for the world.
