“In my own experience, almost everyone hesitates before doing a dangerous or uncomfortable thing. Whether jumping out of an airplane or diving into cold water or singing karaoke in public, very few people can just go for it without hesitation the first time.
This is troubling, because I can guarantee that if you are about to get into a fight it will be unpleasant and uncomfortable and frightening. Even more so if you have never done it before. That’s a recipe for hesitation. If you are attacked, every second of hesitation is a second of damage. The longer the hesitation lasts the more damage you take the less able you become to do anything effective when and if you do act”
