Our mission in this new century is clear. For good or ill, we live in an interdependent world. We can't escape each other. Therefore, we have to spend our lives building a global community of shared responsibilities, shared values, shared benefits.

Effort, not ability, makes the biggest difference in achievement.

Being president is like running a cemetery: you've got a lot of people under you and nobody's listening.

There is nothing wrong with America that cannot be cured with what is right in America.

If you come from a wealthy country with open borders, unless you seriously believe you can kill, imprison or occupy all your enemies, you have to make a world with more friends and fewer enemies - with more partners and fewer terrorists.

I will get things done for America.... Faced with apathy, I will take action. Faced with conflict, I will seek common ground.... Faced with adversity, I will persevere. I will carry this commitment with me this year. I am an Americorps volunteer.
