Presidential leadership needn't always cost money. Look for low- and no-cost options. They can be surprisingly effective.

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.

Don't divide the world into "them" and "us."

Walk around. If you are invisible, the mystique of the President's office may perpetuate inaccurate impressions about you or the President, to his detriment. After all, you may not be as bad as they're saying.

We do have a saying in America: if you're in a hole, stop digging ..... erm, I'm not sure I should have said that.

There are a lot of people who lie and get away with it, and that's just a fact.

When I served as US Ambassador to NATO in the 1970s, the center of gravity in Europe was France and Germany.
