We know that education is the key to unlocking human potential.

As a political spouse, I've found that my stoicism often serves me well.

On the campaign trail, I have the opportunity to meet people from all walks of life - from residents at a battered women's shelter to mentally handicap children to retirees - and learn about their lives and struggles.

Back in 2008, after we'd won the election, no one really expected me to keep teaching. But I couldn't just walk away... So I did both. For eight years, that was my life's dichotomy. State receptions - and midterms. Dinner with the most powerful man on earth - and study sessions with single moms.

My students have shown me so many times that it's not always about being the perfect person in the perfect position - it's about showing up when you're needed.
