Some more thoughts, which may eventually be sucked into a blog post draft:
I think for a lot of people, time spent “doomscrolling” on the news/Twitter/Facebook is worth beeminding. One of my things is the time I spend on Slack – either Slack or Twitter will be the next things I beemind, I think!
For mental health boosting: exercise, yoga, meditation, bedtime/amount of sleep, social time… I think “reading” can be a good one for some people because it’s maybe slower and less over-stimulating than online/videogames/tv.
For a while, when my anxiety was bad, I actually beeminded “leaving the flat”. I didn’t have to do it for long, I just had to leave the building and spend at least five minutes outside, and our balcony did not count. I’ve also beeminded getting dressed before a certain time, since being a freelancer means I can spend all day in my PJs if I want… but it’s not a healthy impulse for me.
I’ve also beeminded compulsive behaviours. Not all of them worked (no skinpicking goal has ever worked for me), but some did (nailbiting worked well, I beeminded “days without biting” rather than “number of times”, which I found too difficult to track). The big winner for me was the number of times I was allowed to ask for reassurance about perceived medical issues (I have health anxiety, which is the polite way to say I’m a hypochondriac) – I had a do-less goal that allowed me a certain number of times per month, which I gradually reduced.
