>What is the best way for me to learn

anime subtitles

stage 1. duration: a couple of months
learn alphabet
install Russian interface on phone or pc, to get comfortable in reading Russian

stage 2. duration: 2 weeks
print out "xxxxx most common Russian worlds" list
check the list out from time to time, try to translate it from memory and check out your progress, it would inspire you, especially on the third day, when you'll see you're actually making surprisingly big progress

print out illustrated prepositions
pin in where you'll easily see it

bookmark the following:
- deepl,
- multitran,
- google.translate, yandex translate,
- google.images, yandex.images,

look for anime with subtitles on yandex and watch them 4+ hours a day for two weeks
space key is pause
never skip any word, pause and translate it, till you get it

stage 3. duration: forever
watch youtube in Russian
watch videos with more rare words, like some technical and scientific videos
bonus: you'd learn the complex stuff that uses rarer words to describe itself

the trick is:
learn most common words
quickly jump over the ebbinghouse curve (learn it faster than you forget it)
learn by repetition
you'll repeat most common words for 10-100 times a day, remembering
but you won't get bored out of learning, because you'd be consuming some anime plot
imagine repeating words 100 times a day without the plot, you'll drop the learning on the next day forever

after two weeks you'll be remembering the core language for 3-5 years, so you'll need to repeat it from time to time, consuming some leisure videos, so again without producing any boredom in the process

remember: learning and studying is different things
you will know how to speak well and understand it well, but you won't know how much cases there are or what's th perfect/imperfect forms, etc.
you'll learn language more or less the same way the natives do
