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.

I'm not a big fan of young kids having Facebook. It's not something they need. It's not necessary.

Politics is a waste of time.

But, as potentially the first African American first lady, I was also the focus of another set of questions and speculations; conversations sometimes rooted in the fears and misperceptions of others. Was I too loud, or too angry, or too emasculating? Or was I too soft, too much of a mom, not enough of a career woman?

Ultimately this issue is on us. We're the ones who make the decisions about what our kids eat.

Wounded Warriors tell me they're not just going to walk again, they're going to run, and they're going to run marathons!

And in my own life, in my own small way, I've tried to give back to this country that has given me so much. That's why I left a job at a law firm for a career in public service, working to empower young people to volunteer in their communities. Because I believe that each of us - no matter what our age or background or walk of life - each of us has something to contribute to the life of this nation.
