As Col. Cooper said, you should teach them to "Ride, shoot straight and tell the truth." For my part, both my kids are excellent marksmen, and will soon be starting training in unarmed combat. Sounds harsh. Well, that's the way the world is.
"As a father of four beautiful kids, I sometimes wonder what kind of world they're going to live in when they become adults. I guess I should start inuring the boys to military life now, eh?"
The greatest gift you could ever give your four little ones is to convince them early on that serving their country before embarking on their life's work is building a fabulous foundation for their own success and character. The Israeli's have it right with their required two years service for both sexes.
