>>76253011 (OP)In any real fight, your brain quite literally goes into animal mode. Conscious thought goes out the window, along with decision-making, and especially what you've seen about fights on TV, in movies, or in a book. You learned how to do a boxing pose once? Yeah, good fucking luck remembering to do that properly in a real fight.
Your mind turns off, you can't think at all. Your eyes are wide open with fear and anticipation. Your heart is beating, your guts wrenching, ready to shit and piss yourself at the slightest drop of a hat. I don't know if I can stress this enough, but YOU NO LONGER HAVE CONSCIOUS THOUGHT IN A SERIOUS FIGHT.
From what I've seen, and I've seen a lot, people just tend to grab their opponents shirt, arms, whatever, and just go in for punches until someone hits the ground (and as I'm sure you've read, pavement is the real killer 90% of the time, not the guy who punched you). What I'm trying to say is, a fight is almost always out of your control once it get's real, and they are very short, often less than a minute, usually far less because someone backs out. I reccomend you read On Combat by Dave Grossman to understand the physiological effects and instincts of combat.
If you want to overcome this, even slightly, you need experience and you need to train, but usually just live through enough fights to get gud. It's no coincidence that guys back in the day who got into fights since childhood, with a good few scars tended to be the most fearsome in adulthood.
Remember, you don't rise up to the occasion. You fall back on your training. Unless you DRILL something into your head until its subconscious (much like the military does), with no thinking required (because you won't be thinking), your brain just goes to animalistic instinct mode, with fear, wrath and sympathy being the only significant factors in determining the normie performance.
