Well at 5-09 165lbs I get out a big ol stick and walk up to the biggest mofo in the group and smack him in the solar plexus and say any one want some of this. I usually get full compliance and they give up all of their dope and guns.
Then when I wake up I use my training and backup and just try to talk to people like, people. You can generally see which ones are going to be jerks. and who's not. There will also be the sneaky ones that you can't read. They can be dangerous. A man/woman has to know their limitations.
You will do things that are scary... Fear is a good thing. You should learn to harness it. It says this is dangerous. Plan accordingly. Don't let it paralyze you.
Me and ol John Wayne are very different in our style.
You will see guys that by their mere presence will have a fight. I've been lucky in that I've managed to "verbal judo" most into being reasonable. When that doesn't work the stick or OC or Mexican Judo is used.
You will die. It's someting we all will do once. It's how we live that makes a difference.
