In 19th century England, there was no law against opium use until something like the 1890's. It was freely available, people didn't talk about addiction but rather about 'bad use of opium'... Charles Dickens used to use it extensively! It wasn't always banned!

MIT was one of the places where molecular biology was born, and I could participate in this enterprise with my own hands.

Too often when we find someone disagreeing with us, our question is about why. Why do you believe this ridiculous thing? What tends to work better is a how question... This kind of approach helps to view the real complexity of a situation and reveals gaps in knowledge.

GDP only catches a slice of the value that we value. It captures what goes on in the market, the financial value of goods and services sold in an economy over a year. In the boxing match between free market laissez-faire capitalists and state loving socialists the economic debate ignored the household – which is expected to provide the food, do the cooking, washing, cleaning, sweeping, education, look after the sick and elderly, yet is completely missing from GDP.

Sustainability isn't a trend in our kitchen - it's a responsibility. We have to think about the future of our planet with every dish we create.

There is very little that matters more in democracy, than truth. I think cynicism is dangerous - that's a self-fulfilling prophecy as well. That's a very dangerous position, and I think we've got to fight cynicism.

I started my entrepreneurship journey straight out of college, and at the time my goal was simple. I didn't want a real job, and I didn't want to wear a suit…. Anything more than that was a bonus.

We have a much more connected marketplace. We have had, what I reckon to be an extremely overvalued stock market since 2000. When you have that situation, you are prone to very sudden negative revaluations.

Undeniably, joining a flourishing company vastly differs from joining a struggling one, just as there's a significant contrast between building a company with the intention to sell and constructing one with the goal of passing it on.

Because it's giving us information about how we're feeling and what we need to do about those feelings. When I'm looking at your facial expressions, I get signals—like either you're interested or you're bored. Either you want me to keep going or not. And that's data for me. Because if I notice a shift in the way you're engaging with me while I'm speaking, I could either use that information, or I could keep going and going and going, and then lose my audience.

30% of people who have life-threatening illnesses don't take their medicine as prescribed, that's mind-blowing. These are not people who have a cold – these are people who are going to die if they don't take their medicine, and even in that situation, compliance is difficult.

The Chinese government has realised that to fuel capitalism, an atheistic, communistic, civil-religion will never propel growth. They realise that their system, frankly, will not support the growth or creativity to create the new technologies and companies that are necessary.
