I'm really bad at self-care lately (because I'm short on time), but: silly phone games, *reading* (which means lots of eBooks on my phone because it reliably goes everywhere with me - I like physical books, but they're not always convenient), photography*, going for walks (as a form of exercise and also a form of calm), tea. I mostly don't have time for soaking baths or going to the Japanese Garden, both of which used to be good for that sort of thing.

* I love it as a hobby, and I'm trying to take and post a photo a day on Instagram. Some are amazingly banal, but I'm trying to force myself to not put it off, and for that it works.
