We have had with Barack Obama some just amazing experiences traveling abroad, being able to introduce our children to the world.... I'm also humbled by the response and the receptiveness, not just here in America, but around the world. There's a part of that warmth and enthusiasm and hope that is surprising and humbling.

I was not raised with wealth or resources or any social standing to speak of.

I try to have no absolute nos. I love french fries, I like a good burger, and I like pie. And that's okay.

In our house we don't take ourselves too seriously, and laughter is the best form of unity, I think, in a marriage.

Find people who will make you better.

We were so young, so in love, and so in debt.

I look at how my kids view exercise. They have a complete understanding that nutrition and exercise go hand in hand. I didn't think like that when I was a kid. But they have a real consciousness about it that I'd like to think comes from the years of attention we've put into this.
