Don't forget to look weird at others like you're angry, if they wear a mask call them "sheeps ha" while walking past them.
Throw trash on the ground, and piss outside instead of going home as much as you can.
Smoke weed outside like you don't care, beat up old people if they call you out on your bullshit.
Stab them, end up in jail, get fked in the arse, kill that person, get a tattoo of a raindrop under your eye.
27years later come out of jail with no job, wish to go back inside.
(Also if you're in a cartel, i guess you need weapons and knife peoples heads off but thats a bit extreme..you should watch those videos, which i don't recommend to anyone..because afterwards you won't wanna be a gangster anymore trust me)
So all in all..be a douche with no respect towards no one, not even yourself.
