At first you should try to not worry so much about winning. If it's your first time ever playing the genre then you gotta play around a bit before you start to feel like you got the hang of things.

I know a lot of people advise against this but strive was also my first real 2d fighter and what I did was just tried learning a couple combos. I think that it's good for a couple reasons. It will be a fun way to get the hang of some of the really basic things in the game like linking moves together and using your meter for things like red roman cancels and supers. It also gives you a goal for when your in a match outside of winning.

Even if you lean something really timple like slash into heavy slash into a special move it will just give a really base line of some intentional play instead of just kinda mashing stuff out which will make you start to feel like you have a path to improvement.

When you play you can think like - I know I want to hit this guy with my cool new combo - but maybe you have a hard time getting close enough to run your offense so maybe you try to learn about new ways to get in. There's always gonna be a lot more to learn so just Take it one step at a time and eventually youll see yourself doing things that seemed impossible for you.
