I think most responses to the above comment are misunderstanding its crux. Learning math (and other subjects in a similar spirit, like physics) is often a frustrating endeavor while you're leveling up to new concepts. IMHO, most of that is because you're thrashing around trying to find the correct perspective that opens up the subject and makes everything obvious. By obvious, I mean not just "this procedure solves this problem" but "this procedure must solve this problem... it couldn't be any other way". Once you're at that level, doing math at that level can be pretty easy. It's mostly conceptual, and doesn't have the tedious procedure that some other fields might involve. The emotional high of that clarity is what keeps a lot of people going through the frustrations along the way. Describing the painful journey without describing what makes it worthwhile is a disservice to readers.
