Too late according to which criteria? Money? Definitely in the biological age when you can reasonably expect to not finish the school alive. And probable a bit earlier age.

Other quotation is for what to use school? If you definitely need a diplom to do what you want to do, that school makes sense.

Of you just want to learn something that is somehow useful, eg. for job promotion, than there are tons of great books, online video courses, many even free or cheap.

One my friend asked me about how to get to university in my country. When I dig deeper, it showed up she even don’t need university for that topic of education and probable would do better without university at all.
