I now see how owning our story and loving ourselves through that process is the bravest thing that we will ever do.

Kids who have an understanding of how and why their feelings are what they are are much more likely to talk to us about what's happening, and they have better skills to work it out.

Waking up every day and loving someone who may or may not love us back, whose safety we can't ensure, who may stay in our lives or may leave without a moment's notice, who may be loyal to the day they die or betray us tomorrow - that's vulnerability.

When we're looking for compassion, we need someone who is deeply rooted, is able to bend and, most of all, embraces us for our strengths and struggles.

The hardest part is to travel, and to be away from your family.

Sidney Farber was a pathologist. He was called a doctor of the dead. He was a pathologist who sort of lived in the basement of the children's hospital in Boston, and he became very interested in childhood leukemia. And Farber began to inject this drug, aminopterin, into young kids, in order to see if he could get a remission.

If what you know and what you love are the same thing, that's great. But if not, write what you love. I love history, secrets, conspiracies, action, adventure, international settings.

I know I haven't spent a lot of time with my children because my job takes me all over the world and takes me away from my children, but I've given them a good education and security. If anything happens to me, my children's future is well-secured. So I think I've done well as a father.
