My happiness isn't connected to my husband's or my boss's or my children's behavior. You have control over your own actions, your own well-being.

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."

Our kids didn't do this to themselves. They don't decide the sugar content in soda or the advertising content of a television show. Kids don't choose what's served to them for lunch at school, and shouldn't be deciding what's served to them for dinner at home. And they don't decide whether there's time in the day or room in the budget to learn about healthy eating or to spend time playing outside.

Fortunately, we have help from the media. I have to say this: I'm very grateful for the support and kindness that we've gotten. People have respected their privacy and in that way, I think, you know, no matter what people may feel about my husband's policies or what have you, they care about children and that's been good to see.

What I tell my kids is, I’m preparing you for college and for life. So, having independence, knowing how to set your own boundaries, figuring out how to make that balance. We still have screen time rules.

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

My experiences at Princeton have made me far more aware of my 'blackness' than ever before. I have found that at Princeton, no matter how liberal and open-minded some of my white professors and classmates try to be toward me, I sometimes feel like a visitor on campus; as if I really don't belong.
