Oh, I can't play soccer, and I'm not a great swimmer. I won't drown, but you won't see me doing laps in a pool.

You see, at the end of the day, my most important title is still 'mom-in-chief.' My daughters are still the heart of my heart and the center of my world.

The work-life balance is a harsh reality for so many women, who are forced every day to make impossible choices. Do they take their kids to the doctor...and risk getting fired? Do they work weekends so they can afford to send their kids to better childcare...even though it means even less time with their families? Do they take another shift at work, so they can pay for piano lessons for their kids...even though it means they have to stop volunteering for the PTA? It just shouldn't be this difficult to raise healthy families.

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.

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.

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?
