Play is a mock version of these activities, allowing us to experiment and understand how they work and interconnect. Questions like 'What if I did it this way?' arise in play, exploring different possibilities.

My learnings came not only from our successes, but a lot of the key learnings came from failures. When you do experience failure rather than to run away from it, you have to sit down and do a good post-mortem and learn from your failures.

When you contrast that with human rights defenders, they are willing to self-sacrifice, to give everything to defend the community… not just their community, but everyone's rights. Why can't politicians be like that?

I define disruption as being where the incumbent players and incumbents somehow deny what their customers are saying or want differently. A disruptor comes in, sees a problem more clearly, and in some cases has more freedom to attack the problem.

Before we came to market, everything in retail was about how cheaply you could pay your employees- and unfortunately, particularly women. There was an attitude in retail that said, '... well, your female employees are just going to get married, have children at 23 and leave, so why invest in them?' The reality of the world was that 60% of university graduates were women- and most women were having children later, entering professional careers.

I remember being on a spacewalk and had a few seconds to see a view that humans were not meant to see. It was like I was hearing from God. But then, I had to get back to work.

Here I am the fool looking to fail frequently. I want to either hit a homerun or walk or even strike out. This means I fail far more often than I succeed. But the important point is that what I lose when I fail is trivial, epsilon compared to what I make when I succeed.

Instead of saying 'I'm a technology entrepreneur…' you might say, 'well, I run a technology business, but I love philosophy and playing the piano…' the person you're speaking to now has a few more dots to connect!

Rather than recruiting someone who assumes they've mastered it all, we seek those who regard their roles with awe. It's essential for us that they are moved by our journey and mission, and harbor an eagerness to learn, not just contribute.

Todays' politicians can't lead public opinion, because they're frightened of it – and we're so consumed by constitutional crises, that there's just no real chance that politicians can give these issues sufficient thought.

I feel it's such a wonderful thing to be able to leave the tyranny of gravity to leave the ground and fly wherever you will.

We are now trapping in the Earth's atmospheric oceanic system dangerous amounts of greenhouse gases which is equal to four Hiroshima sized nuclear bombs per second. Imagine if we had alien spaceships hovering above earth, dropping four Hiroshima nuclear bombs into our atmosphere every second. What would we do? We would drop everything until we got rid of them.
