tbh just find interest in the texts you read - not all of it is going to be really fun and stuff, but remove yourself from the negative connotations and look for interest within the subject. a lot of english is about deconstructing texts to find meaning/ideas/etc, and if you enjoy what you're reading and find joy in that, run with it.
who cares about your teacher and whatever, like english seems useless at times, but i guess its a good way to appreciate literature and how it can add a nice ~philosophical~ element to your education. like superficially, it seems stupid and dumb, but just like ponder a bit more into it and i guess you can try and learn to appreciate what's being articulated in the texts.
also if your teacher sucks, screw 'em like just do whatever. i pretty much bludged through year 11 english and managed to get a 90 for it so it wasn't too bad. i'm not advocating that type of attitude, but when i needed to, i definitely put in the work required. just remember, that english is the 2 units that will definitely count and you want to make them count. if you can't appreciate literature itself, at least find motivation in the fact it will play a role in determining your ATAR, which should be motivational enough if you're aiming high.
good luck
