Barack Obama: “I am looking forward to traveling to Toluca, Mexico on February 19 to participate in the North American Leaders Summit.”

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.

When we choose, when we make that decision, I do believe – and there is evidence for this – that the world gets incrementally better, and that is a worthy goal and it’s worth fighting for.

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

I think when we act on that basis, it doesn't always work out, but over time things do get better.
