“A great teacher will carry anyone”
That is like walking into a gym and hoping the trainer will do the work while your body gets fitter. Both of you have to work — and not at 30%, not at 50%, but at 100%.
“I am not a robot, I cannot do it that way”
It is precisely because you are not a robot that you can learn and change. With every action you understand why you are doing it and where you are going, which means you can work on how effective your learning is. Robots cannot do that: they act mechanically, on a built-in algorithm.

“If I watch films and read, English will come by itself”
Unfortunately, without working through what you have seen and heard, your English will barely change. Yes, your ear will get better, because you have heard many kinds of pronunciation. Your vocabulary may grow a little if you watch a lot. But without carefully working on new phrases, memorising them and using them, English does not move.
Harmony and balance in everything.
