On Sheep, Wolves, and Sheepdogs.

 LTC (Retired) Dave Grossman talks about sheep, wolves, and sheepdogs.

Here is how the sheep and the sheepdog think differently. The sheep pretend the wolf will never come, but the sheepdog lives for that day. After the attacks on September 11, 2001, most of the sheep, that is, most citizens in America said, "Thank God I wasn't on one of those planes." The sheepdogs, the warriors, said, "Dear God, I wish I could have been on one of those planes. Maybe I could have made a difference." When you are truly transformed into a warrior and have truly invested yourself into "warriorhood", you want to be there. You want to be able to make a difference. There is nothing morally superior about the sheepdog, the warrior, but he does have one real advantage. Only one. And that is that he is able to survive and thrive in an environment that destroys 98 percent of the population. 

Read it, its very good.
