The only limit to the height of your achievements is the reach of your dreams and your willingness to work hard for them.

Sometimes the issue is about whether families and communities think girls are even worthy of an education in the first place. It's about whether girls are valued only for their labor and reproductive capacities or for their minds as well. And it's about whether women are viewed as second-class citizens or as full human beings entitled to the same rights and opportunities as men.

You know, you have to start with hope...you don't get anywhere in this country without hope. So it's a necessity. What Barack says is that people have to understand hope isn't just blind optimism. It isn't passive. It isn't just sitting there waiting for things to get better. Hope is the vision that you have to have. It's the inspiration that moves people into action...There are more people engaged in this political process in this year than we've seen in my lifetime. And it is all because of hope because people believe in the possibility of something unseen.

In fact, in the last job I had before coming to the White House - I remember this clearly - I was on maternity leave with Sasha, still trying to figure out what to do with my life, and I got a call for an interview for this position, a senior position at the hospitals. And I thought, okay, here we go. So I had to scramble to look for babysitting, and couldn't find one.

I think in the end, I want to make sure that my kids come out of this thing on the other end in one piece. But I also know that that's how the rest of the country feels as well, so for that I am grateful.

I've always tried to make sure that what I do really connects with the broader agenda of what my husband Barack Obama is trying to do.... But I also find that I have to be very passionate myself about the issue to be able to represent it well. One of the big issues that I've talked a lot about...is childhood health, nutrition and obesity.

You've got to make choices that make sense for you because there's always going to be somebody who'll think you should do something differently.
