i began with the most obvious grammar videos on youtube, pulling out a jlpt list from 5 to 1 when i got confident enough on anki
there is one good set of over 30000 flashies
you skip borrowed english words, start small with vocab, do not get overambitious the first week

you watch more youtube grammar tutorials, when you get frustrated, bored, burned out and disinterested you force yourself to do anki, dont worry about forgetting them the time you close anki, dont worry about relearning basic stuff 10 or a 100 times over

dont worry about sucking at identifying spoken words because 10 words have the same reading
it takes ages to get comfortable to on and kun yomi and memorizing all of them and then mastering so that despite the same sound pattern you know which of the 100 options it is simply based on the context
refer to dejikos nazo keitai for getting raped with misidentifying spoken and read japanese and ateji and other rebuses

it will probably take you long to read fluently in even hiragana at all times
dont worry about it, kanji comes with getting used to the language and wasting enough time on japanese so that you forcibly memorize them
when you are quite familiar with readings and the sounds of kanji your brain will wire them together without you noticing it, dont worry about sucking extremely bad for quite some time

speaking and making sentences comes last, little children barely make sentences, you will be like them for a few years after having a good comprehension of japanese no exceptions
if you do not attempt on talking to yourself in japanese you will never speak it, the human speaking module of the brain is hardwired and not made up on the go
if you do not try building sentences and describing anything even in your own head you will never speak it well
you speak english and make sentences without thinking about it, same is the case for any language, if you do not use it enough then no fast stable and reliable neural paths are made and no speaking is possible

i spoke close to no english some 5 years ago, dont worry about sucking and getting frustrated and dropping all hope for fluency, you will get exhausted and drop learning 10 times in a single month

the prize for learning japanese is a very wide range of loli doujins before someone translates them, navigating nico easily, good philosophy materials and there is a lot of it
i would suggest following the general rule of chans when learning japanese: dont post the first day
otherwise the embarassment will haunt you at nights for all eternity
