To explain to OP, who is likely not here anymore, and because I'm fucking insane, the only thing that will will you to self-teach yourself to learn martial arts is your own drive and fighting spirit, so to speak. If you want to learn, learn from everything. I am not responsible for anything that comes of this information to anyone that comes across it or uses it. You've been warned.
Oh and let me make a disclaimer: UFC style MMA is fucking propaganda based garbage ensured to make people think martial arts are all about turning into primates and humping each other for sport. I'm not kidding. You seriously fucking think that a sport where they bar participants from targeting parts of the body that will cripple them (mainly their careers if anything) or kill them is good to learn fighting? You're better off buying and setting up a targeting dummy or doing professional wrestling or even unsarcastically learn traditional mat wrestling than practice UFC MMA. MMA went to shit since they banned knee kicks and stomping on people and it turned into a spectator sport. Also, nothing is going to stop people on the street from targeting your back or your joints or your face or your soft underbelly no matter how many sit ups you do. Prepare for the unexpected; sport fighting is first and foremost its first predicate. If you like to mix up Muay Thai, Brazilian Jujitsu, and Krav Maga, great for you. Don't go thinking Dana White has your best interests.
Oh, and another thing: Martial arts can be very pretty. It can also get really ugly. Someone said it before but fights come out instantaneously, quickly, and violently. Don't look for shit to get into, but if you do, no one but dickless howler monkeys without anything better to do (ie losers) are the only people that miss out if you run away.
Do not tussle on the ground for too long. Get the fuck back up or learn capoiera or learn ground kicks or learn armbars and legbars and to move your lazy ass off the ground. Height is always the advantage in a fight. I don't care if you know all of the fucking ground games in the world, it doesn't mean shit if you get kicked in the nuts, in the stomach, get curbstomped into hamburger or get stabbed in the gut to tell you someone has a fucking knife too little too late. The only reason MMA has grapple ground games is because they tally points for that. The only thing anyone cares out there is either seeing someone dead or getting out alive. You are close to the grave if you decide to tussle on the ground and try to "position" someone. Fight or fucking die.
I am also going to get into some "wuwu" shit but I feel it's honestly necessary. UFC MMA and the Gracie Family will most likely be the cause of the death of many a meathead making them think the world is like Prehistoric Greece before Pankration where everyone fights like a savage. A mindset like that will get you killed like a stupid blind instinct driven beast too.
On the other note, fighting is about pain. There's no honest truth than that. It is also about walking and confronting that very thin line between life and death. You have to prepare your mind as much as your fitness and moves and whatnot. There are no ultimate techniques to win over anything. There is an ultimate technique for the next moment that comes at you however. Martial arts are all about managing conflict and adapting to what the fuck will come at you in a fight and being aware of all of your surroundings. Of course, I'm likely talking about street fighting too, which is also something to be wise of. Nothing is going to bar another opponent to try and get the upper hand over you. If there's any means to playing fair, then train. Cheap shots to the body are fair if someone wants to cause you more than bodily harm. If someone has a gun, I'll say this, as a karate teacher practicing on a firing range said to a student: Sometimes fist and kicks can't hit far enough.
Listen to your body and soul, not what everyone is trying to measure their dicks to. "The greatest fighting style" all goes to shit when someone is losing their shit mentally or realizes that life isn't fair to them like the other times they had in life. If they can't hone their mind and act like a bull in a china shop, you can see them a mile away as well as all of their openings. Even someone inexperienced in fighting at all but has had enough of someone's shit to be resolute enough to stand tall can take a good shot at someone running off of blind instinct and an unbalanced mind.
TRAIN YOUR MIND. Look up conceptual shit but understand it in your own waking time. Atheist Plus fags and the secular world that runs off of instant gratification is why UFC horseshit claims run the mainstream and all the suckers willing to lap it up. If all you know is bloodlust, someone can hook you like a fish and gut you like one too with it.
Don't go looking for "assassin's fist" or that shit. Outside of "mcdojo macarthyism" where every insecure faggot will point fingers and claim "no u fake" because of Bullshitdo.net, no one ever responsible would ever want a bunch of overcompetitive, egotistic, and powerhungry dipshits who would gladly use violence and strongarmed boasting as a way to get anything in life to ever learn of their style. All martial arts should be treated like weapons and they should act like weapons: no one wants to use them nor plan to, but the act of training to use them to learn to be responsible with them is a good thing, and if they have to be used, pain is a good deterrent, as well as death for more extreme situations. Stay humble; if you wanted to be famous, you should had tried football or boxing.
If I pissed you off speaking about this, good. Centuries of people learning how to defend themselves shouldn't have to crumble because of corporate greed, freeloading egotism, overt secularist materialism, and turning people into animals to ensure people can't fight back because jews or something.
