By the time the United States went to war with Afghanistan in the fall of 2001, I had made three trips to the country. I covered the fall of the Taliban in Kandahar and have been returning routinely for the past 14 years.

I just immediately connect everything to the wars I have been covering overseas, and that's not the case back home. I wrongly assumed all Americans at home were as consumed with our troops in Afghanistan as I was abroad.

And I think that still is true of this business - which is basically research and development - that you probably spend more time in planning and training and designing for things to go wrong, and how you cope with them, than you do for things to go right.
