I had the honor of meeting a young Pakistani woman named Malala Yousafzai, who was shot and nearly killed just for trying to go to school. I also heard about how nearly 300 girls in Nigeria were kidnapped from their school dorms in the middle of the night. There are girls like this in every corner of the globe. In fact, there are more than 62 million girls worldwide not attending school, and that's an outrage.

Some kids have never seen what a real tomato looks like off the vine. They don't know where a cucumber comes from. And that really affects the way they view food. So a garden helps them really get their hands dirty, literally, and understand the whole process of where their food comes from. And I wanted them to see just how challenging and rewarding it is to grow your own food, so that they would better understand what our farmers are doing every single day across this country and have an appreciation for ... that American tradition of growing our own food and feeding ourselves.

I love french fries, I like a good burger, and I like pie. And that's okay. I would be depressed if I felt I could never eat the things that I love. I also don't want my girls to be obsessed about food. We don't have a "no junk food" rule - I just want them to think about their choices.

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

I felt, as a lawyer, when I was mentoring and working with kids, that I gained a level of groundedness that I just couldn't get sitting on the forty-seventh floor of a fancy firm. Selfishly, it gives me joy - it makes me feel like my life has a purpose.

My goal is to be a great-looking 70-year-old! I won't mind being 70, but I want people to say, "You're 70?"

My children are very blessed.... That's why I think that mentoring is such a critical part of the role I can play in this position. I see how little bits of exposure and big bits of exposure really change my girls significantly, and I want that for more girls around the country and the world.
