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.

Look, if you ask a child, 'Would you rather have a fulfilled mother or a stay-at-home Sylvia Plath,' they'll pick Sylvia Plath every time. But I think it's really important that children don't feel their parents' emotional lives depend on their success.

Just because one company is able to succeed with a specific model doesn't mean others will follow with equal or any success.
