Neither of my parents and hardly anyone in the neighborhood where I grew up went to college. But thanks to a lot of hard work and plenty of financial aid, I had the opportunity to attend some of the finest universities in this country. That education opened so many doors and gave me the confidence to pursue my ambitions and have a voice in the world.

For me, education was power.

And a few years ago, when I had the honor of meeting Malala Yousafzai, who was shot in the head just for trying to go to school, this issue got really personal for me. I saw that the terrorists who nearly killed her were trying to silence her voice, snuff out her ambitions, and take away her power.

That’s why I decided to work on global girls’ education as first lady: because right now, there are tens of millions of girls like Malala in every corner of the globe who are not in school — girls who are so bright, hardworking and hungry to learn.
