The thing that makes us so unique is that we, unlike most every other species, have no niche. A niche is an opportunity which a species exploits- and our niche is niche switching. We move from one niche to another, even without major changes to our physical biology.

I use the word ecstasy, which people think means being very, very happy- but in Ancient Greek it means ecstatic, which means standing outside. It's a moment where you go beyond your ordinary sense of self and feel connected to something great and new.

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.

Organizations fail when leaders fail to write-down their own depreciating intellectual capital, and bureaucracies exaggerate that problem by vesting so much power in so few people. Most change management programs are in-fact catch-up programs.

Classic economic theory simply will not allow governments and regulatory bodies to deal with bubbles effectively, as they will grow to tremendous sizes immensely fast, meaning that the amount of support needed when they burst vastly exceeds the value of most economies.

Everyone has a little bit of warrior in them. We all grow up and have a little piece of us which wants to be a superhero, who goes and fights the bad guys. In real life, fighting is tough, you have to overcome your fears – nobody really wants to get into a fight! Escaping that fear is the reason so many people who get into combat sports.

Going to space gave me the opportunity to separate from our planet, but in doing so it allowed me to feel more connected to it than I ever had on its surface in the middle of it all. I carry that with me all the time now.

My observation is if we make a parallel between biology and economics, the role of the economy is like the role of metabolism in an organism. Because what does the metabolism do? It takes in food, resources from the environment, and breaks them down and rearranges them to make other things that we need. Similarly, the economy takes in natural resources from the environment, combines them with labour to make goods and services that we use.

Sports taught me that, rather than be blind followers of rules, we need to constantly question them as to their purpose and validity and be bold enough to change them if they don't serve our value of fair play.

Without the existence of Europe, smaller countries like mine [Estonia] would have a difficult time to survive economically or even from a defence perspective. The internal European market is absolutely vital for the functioning of the very different economies of the continent.

They had a philosophy that we are not here to accumulate, but rather to provide a service to the world- to live a life of service- a service which included education.

The first trillionaires are going to be created through space exploration. Imagine the mineral wealth on planet Earth, and then realise that Earth is just a tiny blue dot in our whole galaxy… which is just one galaxy in a universe, which could be part of many universes. Everything we think is rare on Earth, is abundant in space.
