Throughout my 20s and early 30s, I had jobs that I loved. I worked in city government. I ran a youth organization. I served as an associate dean at a university. And I couldn't imagine how a baby would fit into all of that.

My family didn't have a lot of money, so I worked my heart out to get my degrees. But the minute I graduated, suddenly everyone was asking me, 'Well, when are you going to get married and start having kids?' And the truth is I had no idea how I would balance the expected role of wife and mother with a challenging career.

My mother's love has always been a sustaining force for our family, and one of my greatest joys is seeing her integrity, her compassion, her intelligence reflected in my daughters.

The issues a president faces are not black and white, and cannot be boiled down into 140 characters. Because when you have the nuclear codes at your fingertips and the military at your command, you can't make snap decisions. You can't have a thin skin or the tendency to lash out.

Gosh, I think faith is a wonderful thing. And I even think religion's a wonderful thing. I know a lot of people want to say, 'Religion's the only reason that man has had any trouble at all,' but you know what? World War I and World War II were not fought because of religious reasons.

But what I really believe is education is a key to pretty much everything - prosperity, economics, peace, stability.

I get in trouble when I say things like, 'I'm attracted to violence.' I was a pretty angry kid, and I got into military history largely as a way to vent my own anger. As I got older it narrowed down to a more specific focus on individual violence. I'm just trying to understand where it came from.

In short, it may be said that on paper the obligations to settle international disputes peacefully are now so comprehensive and far-reaching that it is almost impossible for a state to resort to war without violating one or more solemn treaty obligations.
