I kept thinking about this quote from Greg Hamilton
Most people are grass-eaters with their heads down on the ground. The jackals and lions know this and think of them as that. Hold your head up and walk like you are the biggest, baddest lion that walks. The jackals and lions will notice and leave you alone because they don’t want to get hurt. Don’t challenge them because they might feel they have to respond to it. All you want is their respect, not their dignity.

I found it interesting that during the session of showing him how to “walk the walk”, they were also showing him how to throw elbows to the throat and finger jabs to the eyes. I think this is the key part. If you feel capable in your own ability to effectively employ violence, then your mannerisms and the way you carry yourself will reflect that. Great video.
It was interesting and I do wonder how much of that had an impact upon how he carried himself vs. some other aspect of it all.
Nevertheless, it shows… how you carry yourself matters.
