When my kids were younger, I used to avoid them. I used to sit on the toilet 'til my legs fell asleep. You want to know why your father spends so long in the toilet? Because he's not sure he wants to be a father.

When I was growing up I wanted to adopt, because I was aware there were kids that didn't have parents. It's not a humanitarian thing, because I don't see it as a sacrifice. It's a gift. We're all lucky to have each other.

My parents were very poor, but we never felt any sense of need or want. It was a very close, loving, tightly-knit family growing up, and I never felt any sense of deprivation or anything like that.

You can hit my father over the head with a chair and he won't wake up, but my mother, all you have to do to my mother is cough somewhere in Siberia and she'll hear you.

In the fields of southwest Iowa, my parents and grandparents worked and sacrificed. Like so many Iowans, the American Dream for them was never about wealth or fame. Their dream was to leave their children and grandchildren a better life, with greater opportunity, than their own.

It's not ideal to always be one eye on the Blackberry and two arms around my children. For the sake of mothers out there who don't have the Blackberry but do have the children and are hoping someone will be raising their voice on their behalf, it's a great privilege.
