I was thinking about that question earlier, and honestly I usually keep it pretty simple when I need to reset my head after a long day.
I step away from the screen, make something warm to drink, and put my phone in the other room for a little while.
It sounds small, but giving myself a few quiet minutes changes the whole evening and keeps me from feeling scattered.
If I still feel stuck, I tidy one corner of the room, because for some reason a clear space helps me think more clearly too.
I also try not to cram too many plans into one night since I always enjoy things more when the pace stays loose.
By the time I come back to whatever I was doing, it feels lighter and easier to handle.
That routine is not exciting, but it tends to work better for me than trying to force the mood to change all at once.

I finally tried that small habit we talked about, where I prepare everything I need for the next morning before I sit down to relax.
It actually made the whole start of the day feel calmer, and I wasn’t rushing around looking for little things at the last minute.
I laid out my notes, put my keys in the same spot, and filled a glass of water so it was ready when I woke up.
That tiny bit of effort the night before seemed to dissolve a lot of the needless friction that usually throws me off.
I think I resist routines because I expect them to feel rigid, but this one feels more like giving myself a favor in advance.
I’m going to keep doing it for a while and see if it sticks, because so far it has been one of the rare changes that feels useful without becoming a whole project.
