Meh. Eat what the fuck you want, do whatever, you either enjoy life or be miserable like MisterNeon :)
I dunno honestly, I just try to exercise, avoid shitty food and eat what I enjoy, and little things like that. Nothing specific or routine like that
You asked for personal setups so I'll answer with what i have. Jellyfin does my video stuff. TV, movie etc. And for audio I use navidrome. I tried to use jelly for all of it but the music playback sucked (for me). Navidrome is subsonic api compatiable and gives you more options for clients therefore. I even wrote my own tui player :)
If I were you I'd set up jellyfin (not exposed to the internet) and see how it goes. If the music work then awesome, you have a one stop shop for all your media. If not, then add navi on top.
Have fun :)
