Barack Obama: “Your presence both reassures us and fuels our determination for freedom and the right to choose our own destiny.”

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

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

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.

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