I like crotcheting (tried it again for the first time since childhood during Covid). My main problem is that, unless you have already mastered it and can do it in your sleep, I have to fully concentrate on it to not fuck things up, which means I can't do something else at the same time, e.g. listen to an audiobook. And because I'm so slow it takes too much time for me to not think that it's a waste of time because I could have done something more meaningful instead. Objectively, I know it is wrong to think so because the whole point of it is to get away from other stuff and let your brain rest for a while, but it just doesn't work for me and creates extra stress, sadly.
