When it is Go Time, you must have your decision made, already.
David Benke, a math teacher and track coach, had several points to his advantage yesterday when a crazy man* was shooting children at a Littleton high school: he could run, and he could think, and he had at some point made up his mind to do what needed doing. In this story at CNN, Mr. Benke mentions being conscious of how long it took the guy to rack a round in after each shot. He launched his 6'5" frame into the guy, disarmed him, and held him. Yeah, yeah, others helped, and that's good. But who shall bell the cat? Who's first?
Why, it's the person who already decided before it all came down. If you will keep it in your head that you are a sheepdog rather than a sheep, then you are a lot closer to winning than some might think, even when apparently "unarmed."
There are some things worse than dying. I'm glad that David Benke didn't get hurt, but he would still have been a role model if he hadn't been successful in his attempt to stop the attempted murderer.
You are the first responder. Act accordingly.
