If you don't have any fresh ideas, then you use stale tactics to scare the voters. If you don't have a record to run on, then you paint your opponent as someone people should run from. You make a big election about small things.

I think that there is a particular mindset that was on display in the run-up to the Iraq war that continues to this day. Some of the folks who were involved in that decision either don't remember what they said or are entirely unapologetic about the results, but that views the Middle East as a place where force and intimidation will deliver on the security interests that we have, and that it is not possible for us to at least test the possibility of diplomacy.

Robin Williams was an airman, a doctor, a genie, a nanny ... and everything in between. But he was one of a kind.

Keep exploring. Keep dreaming. Keep asking why. Don’t settle for what you already know. Never stop believing in the power of your ideas, your imagination, your hard work to change the world.

If you can look back and say, "The economy's better. Our security's better. The environment's better. Our kids' education is better," if you can say that you've made things better, then considering all the challenges out there, you should feel good.

Just like I described in health care, yeah, somebody comes in, they got new ideas, maybe ideas that are completely opposite of my ideas. Maybe some of it goes, maybe some of that progress goes back. Maybe they think of some things we didn't think of, and so in some other areas - we can learn something.

I will continue to urge creditors to take the steps needed to put Greece on a path towards a durable economic recovery because it's in all of our interests that Greece succeeds.
