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.

Even in these tough economic times, Barack [Obama] has left the VA budget as is so that they're prepared to deal with this influx of men and women who are coming home and dealing with a whole array of issues, not just around mental health but just caregiving and the stresses of reconnecting with families who have been away from each other for a very long time.

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.

Barack knows that we are going to have to make sacrifices; we are going to have to change our conversation; we're going to have to change our traditions, our history; we're going to have to move into a different place.

My sense is that being a First Lady is a full-time job, but I'll know more when the time comes.

All we can do as women is make the best decisions for us. And that includes everything from how you look to how you dress to whether you choose to stay at home or work when you have kids. All those decisions are so personal, and we have to start with finding what brings us joy and what brings us our own individual confidence. And if we're feeling good with those choices, then it makes what everybody else has to say less important.

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.
