Often we're having an argument with something imaginary - a fixed idea of the "enemy" and the good. We need to get beyond that and actually develop a deep curiosity about people and systems and understand them better.

We should look at how "the enemy" - people that you wouldn't necessarily agree with - have done change and see whether there's bits in there that we could learn from.

The question, "When did you last listen to a poor person properly and try to understand what's going on inside their own experience?" enables you to connect.

When you get talking to people in positions of power, you find that often their worldview is framed either in terms of their disciplinary studies at university and/or the country where they first got interest in development.

To be effective at selling ideas, at being a lobbyist, influencing other people, you have to be very sure of yourself.

There's a tendency for people who believe passionately in something to be so convinced of their rightness that if they just repeat themselves a lot at the person, that will convince them. And that hasn't worked on things like immigration or trade deals.

People think there's a single solution to complex problems, and the solution is often making an enemy of a group of people - pulling back and rejecting the other.
