I think self-knowledge is the rarest trait in a human being.

I love children, love spending time with them; I love getting things for them.

I think that we're foolhardy to not be engaging in federal funding of stem-cell research in the most aggressive way we possibly can.

I have three living children for whom this is a father who I want them to love and on whom they're going to have to rely if my disease takes a bad turn.

This diagnosis is a reminder that this is the life you've got. And you're not getting another one. Whatever has happened, you have to take this life and treasure and protect it.

You're young. Maybe there'll be time for a do-over if you don't get it right the first time. But there are no guarantees. There will come a time as it has for me when there's no time for a do-over.

Honestly, I get energized by the crowds. They feed me emotionally.
