If American workers are being denied their right to organize and collectively bargain when I'm in the White House, I'll put on a comfortable pair of shoes myself. I'll walk on that picket line with you as President of the United States of America, because workers deserve to know that somebody is standing in their corner.

You know, one of the things I think you understand as president is you're held responsible for everything, but you don't always have control of everything, right?

I will never apologize for saying that the future of humanity and the future of the world is going to be defined by what we have in common as opposed to those things that separate us and ultimately lead us into conflict.

If we don’t uphold our Constitution and our values, that over time, that will make us less safe and that will be a recruitment tool for organizations like Al Qaeda. That’s what I have to keep my eye on.

The leaders we revere and the businesses that last are generally not the result of a narrow pursuit of popularity or personal advancement, but of devotion to some bigger purpose. That's the hallmark of real success. The other trapping of success might be the by product of this larger mission, but it can't be the central thing.

I accept that people are going to call me awful things every day, and I will always defend their right to do so.

I believe in term limits for presidents because I think that there is no doubt I'm a better president now than I was when I start. I would argue that I am the best president I've ever been over the last year or two. My team is more effective than it's ever been.But what is also true is that number one, this is grueling.
