In the days after the Sept. 11 terrorist attacks, I led a Combat Reconnaissance Aircrew in an intelligence collection mission against North Korea. Before takeoff, I briefed my crew. “Keep your guard up,” I said. “We are facing an enemy that is still at war with the United States. They may think America is vulnerable right now, but that is why we are here. Treat every decision like your life depends on it.”
Benjamin Franklin nailed it when he said, "Fatigue is the best pillow." True story, Benny. There's nothing like pushing your body so far past exhaustion that you'd willingly, even longingly, take a nap on a concrete slab.
