no dude i’m serious
find a team: don’t be afraid to shop around and see what the game’s various characters can do, and find ones that suit your playstyle and/or compliment each other well. do experiment. remember that you can always change your team in the future. there is nothing you can learn about the game that will not continue to help you even if you switch teams. you can change teams as often as you’d like but just make sure that you’ve mentally picked any team you want to get better at playing.
read and watch stuff: character subforums, the SRK wiki, YouTube, the other good fighiting game sites, whatever. anything, everything. if you didn’t know it before then it was worth your time.
practice combos: make sure that you can consistently and reliably “cash in” on all of the damage you deserve when you earn that one little opportunity (or get lucky that one time). do your best to figure out how you will be most likely to land these combos on a clever opponent.
understand defense: make sure u can block good. THIS IS MUCH MORE DIFFICULT THAN IT SOUNDS. try to know as well as you can what your opponent’s offensive options are, and how he will be trying to hurt you (or how he will be trying to run away from you.)
learn matchups: as you play against other people, take special note of how your best options and their characters’ best/preferred options interact with one another. discover when and why you are at an advantage, and when and why you are at a disadvantage. make a concerted effort to remember these things, and to keep them in mind as you make decisions in future matches that you play.
get experience: the more people you play, the more practice you’ll get, the more playstyles and mindsets you’ll see, the more problems you’ll get to attempt to solve, the better you’ll get at recognizing situations and reading people, and the more you’ll get to exercise allll of the other things i’ve already mentioned.
play lots: the more you play, the more quickly you will gain “experience”, as described above.
have fun: have fun!
i hope this helps you. i had a free moment and my fingers were cold.
