get martial arts training from a Sensei
lol. i think you watch so0o much movies.
This topic made me laugh. Had a similar situation like 15 years ago, and let me tell you, and that day I learned I was a beast. Truth be told, I never throw the first punch, because well, the mind can throw way more painful punches any day of the week if you work at it. My advice, be wise, break them down with your mouth, so they fear the idea of getting into a fight with you. Has worked for me since that first time, although every once in a while, someone is too dumb to talk out of their behavior. When that happens, you'll be frustrated enough to at least hold your own.
sooo, did the fight end up happening?
don't overthink it lol, just punch him in the face and if you get hit you get hit, just punch harder.
Don't act like having the first punch is going to win the fight. You need to hit hard and fast, but you can't just swing wildly like a fucking animal. You gotta keep precision and accuracy. Swing first but stay completely ready for him to swing back. Don't think "whew I'll bang him once and that's it" cause if he swing back you gotta be ready to swing again real fast. Keep your damn eyes open and your hands up until it's game over
fight fast, don't think too much about your punches. Use legs, they are much stronger than fists, also you can use knees and elbows. Also, try to parry his punches, if you can.
