Nobody should ever mistake and think that our country [USA] is weakened, or that authority is diffuse and unspecified, and that we are vulnerable.

I don't know why you should be proud of something. It doesn't make you any better or worse. You are what you are.

If you don't encounter setbacks in your career, if you don't have doubts and disappointments , let me tell you, you're not dreaming big enough.

Ten years have passed since a perfect blue sky morning turned into the blackest of nights. Since then we've lived in sunshine and in shadow, and although we can never unsee what happened here, we can also see that children who lost their parents have grown into young adults, grandchildren have been born and good works and public service have taken root to honor those we loved and lost.

And I keep saying, whether you like the president or not, everybody has to pull together and help the president because, as the president goes, so goes the country, as the country goes, so goes your job, your ability to feed your family, your government.

There will be ups, there will be downs, there will be sideways. I can just tell you I have been hired, I have been fired, I have been lauded, I have been vilified. I've said some of the most brilliant things that just by accident appeared on my tongue, and I've said some of the dumbest things that you could imagine. But each day - even the day that I knew I was going to be fired - I looked forward to because I've always believed that tomorrow was going to be the best day of my life.

I'd love to have a president who really was out there leading and traveling around the world campaigning for joint climate change action. Even the Chinese government is trying to get people to stop polluting. And I think the federal government level in China is acting more responsibly than the American government.
