I think what you need my friend is some self confidence. Instead of resorting to weapons, I feel like you should pick up boxing or something of that sort, like a self defence class. Now this doesn't mean that after you pick up that martial ass class you will start to kick everybody's ass, cause you aint batman, only batman does that shit. Biggest life tip I can tell you is to mind your own fucking business. No, its not a joke. My rule of thumb is only intervene if someone is getting their ass kicked, otherwise let them be. If you go about your business, without looking at people and by simply being aware of what is going on around you, you will be fine.
