Only tangentially relevant but had a discussion earlier today in which it was pointed out that spaced repetition learning like Anki decks are always miserable since you are constantly exposed to the things you are bad at and rarely see the items that are easy for you. More generally you might observe that it always feels like you suck at things you are trying to improve at because you are (presumably, ideally) challenging yourself.
