The top-voted reply by TillWinter may be excellent but it actually doesn't answer the question posed by the OP. TillWinter's reply is mostly about the "divide-and-conquer" approach to learning. Yes, efficient study habits are good to know but that type of answer can be generically applied to any learning endeavor.

The reddit OP is asking about specific resources that help with intuition. In contrast, many math teaching materials work from an analytical and symbolic approach (e.g. axioms and properties.) Unfortunately, most people can't truly learn intuition that way and they end up in mindless "plug & chug" to pass the test.

you should link to the reply instead, because the most upvoted reply might change.
