I'll never forget what some dude told me at a bar once, I went home and thought about it for a good length of time and tried to discern whether or not it had any validity.
"When you stop fearing being feared, you will be the edgiest (He said scariest) guy around."
I don't think it's something that you radiate consciously; any attempt at that can be smelled by the strong. It's like Thor's hammer "he who wields this hammer..." yada-yada.
You need to KNOW that if shit popped off, you will start snapping motherfuckers in half. I have sociopathic tendencies, but I chose to do some serious fucking work on myself and channeled it towards people who were being a nuisance or actually hurting other people physically. Girls tell me that they "love my protector side, that I'm a lion waiting to pounce on things, that they can see the fire in my eyes." I don't project fire in my eyes, I am fire in my eyes.
I believe everything is related and has some minor truth (except for some minor just banana-crazy ideas), being the god of war of the zodiac, fearless-no-stopping-till-someone-dies fighting has always been pumping through my veins - now it's more controlled, though.
I recommend some boxing or muay-thai, it hurts, but it's a toughness-building kind of hurt. Shit, hockey will do the trick. Also, it's not about being a bully, it's about knowing you can destroy the bully, the nuisance, the burglar, the pesky fly of a person that passive-aggressively fucks with everyone >
Literally, live on!
