Plasma 6 started very prone to crashes in my laptop when it released. I like how it works a lot more than Gnome, but Plasma tends to be buggier for me too.
This last month I've been having rendering issues in a lot of software, like Firefox and Okular in Fedora 41 (and now 42). I don't know where they came from as it was pretty much perfect last month.
Sometimes I think I'd prefer to return to xfce in laptop (like I tend to use in desktops) or use labwc.
A thing that has helped me a lot is to go buy food when I'm not hungry. It reduces my chance of overeating and buying lots of food, also making me spend less money.
When I used to cook a lot for myself in uni it helped a lot to plan meals.
