less than 45 should be 'too cute' because when you multiply them by '2' they are still a'cute'

Numbers are the most primitive objects that contain nothing else in them so I should have used that in the example because letters can represent sets

left hand side depends linearly on $\theta$ but the right hand side doesn't :^)

OK. the ordering of all of this stuff is basically up to the textbook author, it doesn't come from heaven

One disadvantage might be its sheer size (which is not strictly a downside of course). But if you want to go deeper in algebraic subjects, there is a point where you want to switch from "general abstract algebra" books like Lang's to more specialized stuff like more advanced group theory, commutative algebra, non-commutative algebra, representation theory, homological algebra, algebraic NT, algebraic geometry etc.
The point I'd make is that it's by no means necessary to read a ~900 pages book on "general abstract algebra" before you make that switch to more specialized stuff

@Derso golden ratio is a really good marker. if you're watching something and somebody says "golden ratio" you just switch away

If you have to go back and review everything you once knew before starting to study something new, will you ever study anything new?

I will also argue that this eventually fails, because you eventually start reading work where the lines of attack are not obvious (e.g. many research papers).

if i picked up a book written in arabic i wouldn't be able to read that either, and i wouldn't think "oh my god, i'm such an idiot, i will never accomplish anything." i'd just need to study arabic if i cared about reading that book. a lot of math books in one's native language are maybe closer to this analogy than most people might think

yeah pie as jakobian mentions a lot of it is just differences in how people are built. it really helps if you don't conceive of math as a kind of battle or test of general intelligence. also, to adjust expectations downward. why would anybody expect to be able to instantly understand a subject they had maybe never read anything about
