Obviously losing a fight gets you hurt, killed, or humiliated, but winning a fight sucks too.
Even if you're the best fighter in the world, it's still not worth it.
1. Even the winner typically takes some damage.
2. The people who have egos that get them in fights are the same people whose egos can't handle losing, so after you win, they'll come back with a knife/gun.
3. The bitch move of having your friends jump in to help is no longer shameful to these idiots, so expect to be fighting 3 or 4 dudes at once.
4. The other bitch move of playing the victim when the cops arrive and filing a lawsuit has also been normalized, so if you win then you're likely going to face legal consequences.
5. It never ends. Even if you make it through the first 4 steps, there's a never-ending line of idiots that are happy to make you go through them again, and again, and again. At some point you have to realize you're either going to have to keep fighting forever or learn to de-escalate.
You don't have to accept every invitation to a fight.
Obviously, there are self defense or family defense scenarios where you have to fight. So definitely don't choose flight in those instances. I will say for girlfriends though, often they're not worth defending. So many women start shit and expect their man to finish it for them.
