But the truth of the matter is, we're an open society, we want to remain an open society, and there will continue to be vulnerability. That's why we have to meet the threats when they are not yet taking place on our territory and on our soil.

Spirituality and faith are at the core of who I am. I was born to deeply religious parents who were able to give me that rock solid foundation in the church and in my faith which really has served me so well.

I'm very glad my mother didn't let me quit piano lessons at age 10. She said I wasn't old enough or good enough to make that decision, and she was right. I remember at the time I was shocked. I did not like that my mother said those things to me. But when I got a chance to play with Yo-Yo Ma or more recently with Aretha Franklin, I thought, I'm really glad she said what she did.

I firmly believe you never should spend your time being the former anything.

I grew up in a very loving middle class family. My parents were educators. I'm not even the first PhD in my family. They tried to shield me, just as other parents in my neighborhood tried to shield their children. But you knew there was a reason that you couldn't go to that theme park or to a movie theater or to a hamburger stand. They couldn't shield you completely. What they did though was they never let it be an excuse for not achieving, and they always said racism is somebody else's problem, not yours. They tried in that way not to make us bitter about Birmingham.

I've never really been a workaholic.
