I did attempt to find out if there were any secret government documents that revealed things. If there were, they were concealed from me too. And if there were, well I wouldn't be the first American president that underlings have lied to, or that career bureaucrats have waited out. But there may be some career person sitting around somewhere, hiding these dark secrets, even from elected presidents. But if so, they successfully eluded me...and I'm almost embarrassed to tell you I did (chuckling) try to find out.

The seven principles of Kwanzaa - unity, self-determinat ion, collective work and responsibility, cooperative economics, purpose, creativity and faith -- teach us that when we come together to strengthen our families and communities and honor the lesson of the past, we can face the future with joy and optimism.

We live in an interdependent world. Every time you cut off somebody else's opportunities, you shrink your own horizons.

Without a high pain threshold, you can't be a successful President.

You don't have to wait till your party's in power to have an impact on life at home and around the world.

When you get asked hundreds of questions, it's not possible to remember the answer to every one.

The great thing about not being president anymore is I can say whatever I want, about anything. Of course [now], nobody really cares what I say. And now I have the worst of all worlds -- my wife has become the secretary of state, so no one really cares what I say -- unless I mess up.
