I dunno, I'm objectively fairly good at maths (I got a first in the Cambridge MMath), but the reason I learned so much from the course was because I spent almost the entire time failing miserably to get anywhere on problem after problem. Sure, eventually you make the breakthrough - but only after hours of failure. Every avenue you try that doesn't work out is a frustration - often a blank-wall kind of frustration - and there are lots and lots of them before you succeed. Further, every avenue I try feels equally fruitful at the beginning, and frequently reaching the end is highly nontrivial even when you're on the right path, so "if it feels hard, you're on the wrong track" isn't a very easy thing for me to apply.
