Barack Obama: “Focusing your life solely on making a buck shows a poverty of ambition.”

Use that hope to make a difference. Get involved.

I’m going to insist that we can do better than we’re doing right now.

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

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.
