In my favourite guide on how to start taking better care of your home, which I have yet to successfully implement, they give one tip which I love: whatever you do, no matter how hard it gets, do not stop doing the dishes. Clean the kitchen every day no matter what. Pull back on everything else if you have to.
This is great advice on its own but I think it is also a deeper wisdom: when seeking to improve, don’t let yourself neglect the basics. The basics never stop being important. Let them slip and it all goes downhill terrifyingly quickly.
