Barack Obama: “It's my belief that this country has always grown when it grows from the bottom up.”

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

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

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

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.
