step 1: learn kana (important)
step 2a: learn basic vocabulary (just pick a random shitty anki deck like this or this and drop it when you get bored)
step 2b: learn basic grammar (just read tae kim)
step 3: watch anime (without english subtitles, this is important, there are many loser weebs who have watched thousands of hours of anime and dont know japanese for shit, this is the fault of english subtitles, not anime itself)
step 4: watch more anime
now youve gotten this far just do what you want wont matter as long as its in epic nihongo
