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.

And let's be clear: It's not enough just to limit ads for foods that aren't healthy. It's also going to be critical to increase marketing for foods that are healthy.

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.

I know what it feels like to struggle to get the education that you need.

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.
