What I believe unites the people of this nation, regardless of race or region or party, young or old, rich or poor, is the simple, profound belief in opportunity for all - the notion that if you work hard and take responsibility, you can get ahead.

Jobs was brave enough to think differently, bold enough to believe he could change the world, and talented enough to do it.

The forces that divide us are not as strong as those that unite us.

America can do and has done big things when we work together.

[The White House staff] start bringing in their kids, who you think should be babies and now are in second grade or something, and you've watched them grow up.
