I'll never forget coming home after covering Sandy Hook. Seeing the faces of family members. The firefighters who could never unsee the unthinkable. Those tiny caskets. I came home, sat in my dark apartment because I didn't even bother to turn the lights on, and wept.

There are often days when I've sat down in my office for hours and prepped for a show knowing, three minutes before I go on, some big crazy thing happens where everything is thrown out, and the teleprompter goes blank.

I got my first migraine on my first day of work in TV in 2001... it was debilitating.

What does 'home' really mean? Is it merely geography, where you were born? Could it include straddling two continents and cultures? Or perhaps it's a place with a spiritual magnetism - a feeling toward a culture or people - that's tough to put into words?

When I'm covering a story, it's not just about gathering facts, but it's gathering the human element as well.
