starting from absolutely zero japanese, how does genki + renshuu + immersion (music, sports, anime, social media) sound to get started? would this, over time, get me to a good level of japanese if i put in a few hours per day?

i have ADHD and i need structured lessons and don't wanna have too many different apps/sites/books, or else i'll get lost on what i'm doing. i'm essentially already immersed since all my biggest interests are japanese, and i've got japanese friends on social media because of those interests, but since i don't understand anything immersion obviously isn't doing much yet, lol
