It is worth reminding that being president is a tough job for anybody, and particularly so in the information age. There's such a glut of information. Anything a president says or does is picked up on the Internet or the 24/7 news media and criticized almost instantly. Leaders persuade through their words and as such their words need to be measured and well chosen. It is a tough job.

From where you sit, the White House may look as untidy as the inside of a stomach. As is said of the legislative process, sausage-making and policy-making shouldn't be seen close-up. Don't let that panic you. Things may be going better than they look from the inside.

The absence of evidence is not necessarily the evidence of absence

We never believed that we'd just tumble over weapons of mass destruction in that country.

Whatever new threats and challenges may emerge, our nation will be able to face them squarely, deal with them, and yet allow our people to continue to live free and unafraid. The decisions you make, the courage and creativity you bring to your responsibilities, will determine America's future. Liberty and our way of life are fragile gifts - their care is in your hands. We thank you for stepping forward to shoulder that immense responsibility. Your country is grateful, and proud of each of you.

In our system leadership is by consent, not command. To lead a President must persuade. Personal contacts and experiences help shape his thinking. They can be critical to his persuasiveness and thus to his leadership.

"Do you have any regrets?" Of course I do.
