But when it comes to claims like 'pets alleviate depression,' there's really no solid evidence. In fact, the findings so far are pretty ambiguous. And in one study that found no significant overall effect, cat owners were actually more depressed than the control group.

When you gaze into your dog's eyes, your oxytocin level—the so-called 'love hormone'—rises, and the same thing happens in your dog. It's a powerful pair bond. More recently, though, researchers have found the same effect with cats.

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.

We have to get out of this 'tax to spend' mentality and think about using resources to create investment funds that support local businesses, while also expecting to get something back as those businesses appreciate.

Knowledge isn't just stored in people or the sum of individuals; knowledge exists in the network. The labour market is always searching for those matches, constantly learning because technology changes and people retire, keeping the system out of equilibrium.

There is an honest trade-off between labour market protection and learning. If you have an extremely static labour market—like the high protection laws in France or Spain—you get stability, but you sacrifice learning. You pay a 'learning cost' for that 'stability dividend.'

When it comes to the growth of knowledge, you need to double down on the capacities you already have; you want to build on cities that possess a foundation. When you build in a remote location, costs skyrocket, attractiveness is hard to engineer, and the complementarities that help knowledge stick to a place simply aren't there.

Our vision is something we call 'SETI of the mind.' The goal is to treat the DMT space and other altered states as novel domains to be explored, much in the same way we treat outer space.

We assumed matter was fundamental when we probably should have prioritised consciousness. If we viewed consciousness as the prima materia of reality itself, I think we'd know a lot more about these intelligences and hidden agents than we do today.

We never have direct access to the world in itself; we only have access to the model our brain is constructing. It works as a sort of 'best guess.' The brain isn't trying to find the absolute truth or create a perfect replica of the outside world's structure.

It forces you to confront the fact that we know almost nothing about the true nature of reality. Whatever image you have of what's real or possible is obliterated in an instant. You're faced with a world that isn't just strange, but so utterly incomprehensible that it transcends imagination.

Don't give away a majority shareholding the way I had to with HomeServe. I ended up giving away 52% of the shares with my partner for a £500,000 investment we took when we'd run out of money—a terrible time to raise capital.

You absolutely need some funding to get started. But ideally, that should come from remortgaging your house or borrowing a bit from friends, family, or parents—just enough to have a small amount of money, but not too much. That way, you can copy, pivot, test, learn, and prove out your model on a small scale.

How many times have we all heard someone say, 'I had a really good business idea, but then I found somebody else had already done it—so I gave up'? I'd say the opposite: fantastic! If someone's done it, is still in business, and it's working, that's proof you're onto a solid idea.

I think people need to understand that building a business is really, really difficult. That shouldn't put anyone off, but there's no easy road to riches.

For a long time there was a kind of cultural chauvinism: the idea that if you just played Mozart to people in the Amazon or to hunter-gatherer groups in the South Pacific, they'd instantly recognize its greatness, maybe even see God. But of course, they don't experience it that way at all.
