I joke that I stick with the job because it covers my insurance, but the reality is that my career has always been very important to me.

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?

Barack and I have been in the public eye for many years now, and we've developed a thick skin along the way. When you're out campaigning, there will always be criticism. I just take it in stride, and at the end of the day, I know that it comes with the territory.

I come here today as a Christian, a person of faith who believes we've all been called to serve our fellow men and women and to honor God's creation. We want our girls to know right from wrong, to always tell the truth, to treat people no matter who they are with dignity and respect, no matter how different they may seem...because we want our girls to know we are all God's children and there's so much more that unites than divides us.

The arts are not just a nice thing to have or to do if there is free time or if one can afford it. Rather, paintings and poetry, music and fashion, design and dialogue, they all define who we are as a people and provide an account of our history for the next generation.

I tell my kids, 'I am thinking about you every other minute of my day.'

To be a good parent, you need to take care of yourself so that you can have the physical and emotional energy to take care of your family.
