It’s easy to try to exaggerate the problems just to get more attention. So for me, it was very clear that the best way to deal with that was to do the best science that I was capable of doing.

It went from publisher to publisher to publisher. All of them refused it. They gave the same reasons, until a small publisher picked it up. From 1960 to 1963, three years, it didn’t sell 1500 copies. Nobody wanted to read it. It doesn’t matter. I am not here to sell, I’m here to write.

The highest form that civilization can reach is a seamless web of deserved trust. Not much procedure, just totally reliable people correctly trusting one another. That's the way an operating room works at the Mayo Clinic. If a bunch of lawyers were to introduce a lot of process, the patients would all die. So never forget, when you're a lawyer, that you may be rewarded for selling this stuff, but you don't have to buy it. In your own life, what you want is a seamless web of deserved trust. And if your proposed marriage contract has forty-seven pages, my suggestion is you not enter.

I don't enjoy it but I know that I have got to live with [myself] if I'm not going to give it 100 per cent. The key thing is getting to the start line and knowing that I couldn't have done any more, that I didn't back off. You accept the pain, because if you didn't there would always be that element of doubt.

And I'm not here to say that men are to blame for the crisis and what happened in my country. But I can surely tell you that in my country, much like on Wall Street and the city of London and elsewhere, men were at the helm of the game of the financial sector, and that kind of lack of diversity and sameness leads to disastrous problems.
