Barack Obama: “I am absolutely optimistic that we've got everything it takes for us to succeed in the 21st century.”

If I had a blame pie for why politics is so polarised and why we're seeing a rise of populism in many places, it's because of that information that is going into our brains every day.

And I will fight for that, even if I don’t always think it’s going to win.

People need to “rediscover what’s the story we tell about how we’re going to live together, and see each other, and recognise each other, and disagree, and yet, still care for each other”.

It is a decision about how do we face and embrace this finite amount of time we have on the planet.
