Salman Abedi, Khalid Masood, Khuram Butt, all of these people and the people in ISIS, Al Qaeda, Boko Haram, Al-Shabaab… We tend to think sometimes that they are extremism. But the reality is they didn't breed extremism. Islamist extremism bred them.

Women account for a mere 0.5% of recorded history.

The laws of cause and effect which govern our universe don't care about our beliefs – so we'd better find out what those laws are and try and align our beliefs to them to eliminate guesswork. The consequences if we don't? we'll get sick, we'll starve, our machines will break down.

If somebody told me the US stock market returned 12% per annum over the last 50 years, I would simply ask them what the returns were over the last 150 years, 250 years, 10 years and so on. I could make up any return I want just by picking the appropriate time period.

To make those markets work well, they have to make the market thick, they have to attract enough participants to get good transaction levels. They have to deal with the problem of congestion that can be symptomatic of thick markets. You have to also make the market safe enough for people to transact in!

Nothing prepares you to actually see the Earth from space. I spent more than 7 months in space, and even on my last day that view never got old.

There's also a danger in acting of identifying yourself as an actor. We have to try to identify ourselves as human beings first, and our jobs second. I'm Sam, I act sometimes… not I am Sam, I am an actor.

What we're seeing is a broad constellation of nominally independent subsets, even entire industries, that have now come under the umbrella of the foreign lobbying industry. All of these entities have been transformed into go-to vehicles and mouthpieces for foreign regimes.

From 20,000 miles away however, you couldn't see any civilisation- just the land mass and those three colours… the brown of the land, the white of the clouds and the ice, and the crystal blue of the ocean. Earth was just suspended in the blackness of space and it was an incredibly beautiful sight.

We took bold risks with unconventional styles and vibrant hues, but the crux of the matter remained that our marketing image always resonated with a particular sense of cool. It created this compelling narrative: if you owned a pair of UGG boots, you were undoubtedly cool.

Chosen suffering is part and parcel of a meaningful life. If you don't have any chosen suffering in your life, you're probably not living the best life you could. To put it primitively, we're the mammal that likes Tabasco sauce! We're the only creature that seeks out suffering and pain willingly.

Identities are useful – if you had to make everything up in your life, from the start, with no input whatsoever – that wouldn't be freedom – you'd be less free; you'd have to think constantly about what you should or should not do. There would be no structure for your life choices.
