The take-away quote is, “Do not let yourself be crippled by something that only exists in your mind.” The chapter ends by looking at decision-making at the speed of a fight, which is pretty quick.
This is a common problem we all experienced at the Lethal Force Institute when Maloney and me attended the 'duelatron' scenario with loaded.45 pistols and put through a variety of situations where even though the adrenaline kick occurred, it was nothing like it would be in a real situation where someone is trying to kill you.
And yet, even then we had trouble thinking and making the right decision...which on the street it would prove fatal...where you find yourself unable to think rationally...something else we , the 'High Coffee Dans' deny constantly.
It all looks good/sounds good/on a friendly dojo floor...but once you are out on the streets, and some punks decide to kill you...the person you were in the dojo has Just left town...leaving some pair of jeans tripping over trying to get into sanchin while you are taking a knifing.
