And in my own life, in my own small way, I've tried to give back to this country that has given me so much. That's why I left a job at a law firm for a career in public service, working to empower young people to volunteer in their communities. Because I believe that each of us - no matter what our age or background or walk of life - each of us has something to contribute to the life of this nation.
I love that for Barack, there is no such thing as 'us' and 'them' - he doesn't care whether you're a Democrat, a Republican, or none of the above... he knows that we all love our country... and he's always ready to listen to good ideas... he's always looking for the very best in everyone he meets.
As a mom, I know it is my responsibility, and no one else's, to raise my kids. But we have to ask ourselves, what does it mean when so many parents are finding their best efforts undermined by an avalanche of advertisements aimed at our kids.
For the first time in my adult lifetime, I am really proud of my country. And not just because Barack has done well, but because I think people are hungry for change. And I have been desperate to see our country moving in that direction.
I've seen firsthand that being president doesn't change who you are. It reveals who you are.
It wasn't so long ago that I was a working mom myself. And I know that sometimes, much as we all hate to admit it, it's just easier to park the kids in front of the TV for a few hours, so we can pay the bills or do the laundry or just have some peace and quiet for a change.
I'm not asking any of you to make drastic changes to every single one of your recipes or to totally change the way you do business. But what I am asking is that you consider reformulating your menu in pragmatic and incremental ways to create healthier versions of the foods that we all love.
I never cut class. I loved getting A's, I liked being smart. I liked being on time. I thought being smart is cooler than anything in the world.
You may not always have a comfortable life and you will not always be able to solve all of the world's problems at once but don't ever underestimate the importance you can have because history has shown us that courage can be contagious and hope can take on a life of its own.
And I love that even in the toughest moments, when we're all sweating it - when we're worried that the bill won't pass, and it seems like all is lost - Barack never lets himself get distracted by the chatter and the noise. Just like his grandmother, he just keeps getting up and moving forward... with patience and wisdom, and courage and grace.
The truth is, in order to get things like universal health care and a revamped education system, then someone is going to have to give up a piece of their pie so that someone else can have more.
See, that's why Barack's running: to end the war in Iraq responsibly - to build an economy that lifts every family, to make sure health care is available for every American - and to make sure that every child in this nation has a world-class education all the way from preschool to college.
My mother's love has always been a sustaining force for our family, and one of my greatest joys is seeing her integrity, her compassion, her intelligence reflected in my daughters.

Together, we can help make sure that every family that walks into a restaurant can make an easy, healthy choice.
I am so tired of fear. And I don't want my girls to live in a country, in a world, based on fear.
The problem is when that fun stuff becomes the habit. And I think that's what's happened in our culture. Fast food has become the everyday meal.
The fact is, with every friendship you make, and every bond of trust you establish, you are shaping the image of America projected to the rest of the world. That is so important. So when you study abroad, you're actually helping to make America stronger.
If my future were determined just by my performance on a standardized test, I wouldn't be here. I guarantee you that.
You may not always have a comfortable life and you will not always be able to solve all of the world's problems at once but don't ever underestimate the importance you can have because history has shown us that courage can be contagious and hope can take on a life of its own.
And I come here as a daughter, raised on the South Side of Chicago - by a father who was a blue-collar city worker and a mother who stayed at home with my brother and me.
You may not always have a comfortable life and you will not always be able to solve all of the world's problems at once but don't ever underestimate the importance you can have because history has shown us that courage can be contagious and hope can take on a life of its own.
We learned about honesty and integrity - that the truth matters... that you don't take shortcuts or play by your own set of rules... and success doesn't count unless you earn it fair and square.

And Barack and I were raised with so many of the same values, like you work hard for what you want in life. That your word is your bond that you do what you say you're going to do. That you treat people with dignity and respect, even if you don't know them and even if you don't agree with them.
I am an example of what is possible when girls from the very beginning of their lives are loved and nurtured by people around them. I was surrounded by extraordinary women in my life who taught me about quiet strength and dignity.

Clearly this is a tough economic time, and a lot of families are hurting. So when we talk to parents, we talk about small changes for kids and things that don't cost extra money. Like adding water and eliminating sugary drinks and sodas. That's going to save money right there. Or adding a few more vegetables.
