It's not every man's job to fight, but it's every man's duty to protect. I would never want to fight or get into an altercation at all, but I equally don't want to be defenseless when trouble comes my way. Or god forbid if it came a loved one's way. How about trouble just stay in its own lane?
If you can't afford to go to a karate or krav maga school, at least look up some online videos and do push ups. You want to have the confidence to warn a guy not to come any closer, knowing that if he does you can light him up. There's no better feeling than that confidence. Well, there's the feeling of going to a party and not fighting at all. That's a better feeling, but you know what I mean.
