You know, I have seven children, so I guess I know some things about life.

When I was growing up, my parents were almost involved in various volunteer things. My dad was head of Planned Parenthood. And it was very controversial to be involved with that.

I thought I was grounded. I thought from my kinda blue-collar outlook on life that I would call myself a grounded person. I was not. I was like a balloon flying around in the air. And as soon as our first child was born, boom - my feet came right down to the ground.

There have been times in my life when I wondered about God's existence. When Prince smiles, when Paris giggles, I have no doubts.

Up until I became a father, it was all about self-obsession. But then I learned exactly what it's all about: the delight of being a servant.

When you're a parent, you sing better. It becomes a pure pleasure, rather than something I have to do.
