The hardest part of it was really being away from my family - I have two small children. Last year I took over 20 business trips, so being away from them was hard.
The military is a very cool world to write about. I went down to Ft. Benning, Ga., for military training, and I learned a lot about soldiers and officers and why they joined up and what their life has been like.
No man ever became great or good except through many and great mistakes.
