I want to feel like the things I did made a difference. That's one of the reasons I spend time greeting people on rope lines, because I'm always thinking, 'Maybe this interaction, particularly if I'm meeting kids, will change someone's life.' That's how I think about the work I do as First Lady. It's a rare spotlight. I want to make sure I don't waste it.

When I get up and work out, I'm working out just as much for my girls as I am for me, because I want them to see a mother who loves them dearly, who invests in them, but who also invests in herself. It's just as much about letting them know as young women that it is okay to put yourself a little higher on your priority list.

I'm trolling through the recesses of my mind for the things I did with my kids when they used to like to do things with me. They don't want to be around me now. I look back on these times - all those little funny pottery dishes that you'd pay for, and they'd paint, and they were ugly, and you glazed them, and you'd go back, pick them up, and it's like, "Oh, now I've got to put this on my desk." There's all that kind of stuff.

I hate fund-raising. Haaaaate it. Hate, hate it.

I mean, that's the least we should do for these men and women [veterans and military spouses], is to make sure they come back to jobs that pay, to career opportunities, that these spouses are able to add a second income to their households, because these families do not have a lot of resources.

Let Girls Learn issue has always been personal for me. I grew up in a working-class neighborhood on the South Side of Chicago where most folks, including my parents, didn't have college degrees. But with a lot of hard work - and a lot of financial aid - I had the chance to attend Princeton and Harvard Law School, and that gave me the confidence to pursue my ambitions.

I was an incredibly devoted student, and I would often wake up at 4 or 5 in the morning to study. But even so, there were still people who thought that a girl like me with a background like mine wasn't really "college material."
