Barack Obama: “Just as our predecessors stood united in pursuit of that vision, so will we.”

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

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.

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