Thanks for the warning!!
I do think though it’s good to know the general rules and then try to get the exceptions, like others have mentioned. Like in german, I can only learn which noun is which gender through the rules: most chemical elements are neutral gender, but some are masculine; alcoholic drinks are usually masculine gender, but beer for some reason is an exception and is neutral, etc. There always is some execption to the rule…
However, it could be really bad to generalize something that has too many exceptions and does not cover the majority of the cases. I remember an american I once met that made plurals of portuguese words ending in “-ão” to “-ões”. But plural ending form of words that end in “-ão” could be also “-ães” or “-ãos”. Unfortunately it’s all very irregular and there really is no main ending. He was always very confused…
The Genki textbook has some reading sections that are level appropriate, for example.
I’ve read so many great things about it, but I’m such a cheap person! I feel like with everything that is available on the internet, I should be able to learn without spending much. Wanikani and the HumanJapanese app are the only things I’ve spent money on so far, and I’m really not planning on spending much more (although I know the textbook would probably be more of an investment then “spending”; but I can’t help it, my parents are so cheap as well, I was raised like this!)
I’ve found some free Tadoku books, and a lot more here:

It’s amazing how easy NHK Easy really does become at a certain point. I’ve now picked up manga I struggled to read in the level 20’s and breezed through them (comparatively!) now.
That’s SO great to hear. I felt really bad when I could only understand a couple of words in NHK easy. I’ll come back to it in a couple months!
