I dont get ”remembering the kanji" book
isn't it just better to pick kanji up as you learn vocab than it would be memorizing abstract radical component concepts?
Or is there a certain point where that is the faster way past x amount of known kanji? I mean so far I'm been picking up radicals on my own.

to me its like learning mental math tricks implicitly as you go, vs common core cancer trying to teach them ahead of time explicitly.
