Playing any musical instrument. The feeling of your practice grindings pay off, no matter how still mundane it is to compared to social media professional musicians, is a pretty good feeling.

Life is pretty boring, which is why content addiction works... :/

Go for out to an interesting place and take some cool photos.

Building things. Legos are super fun.

Drawing and reading are both time consuming, cheap and good stuff that can make you grow too. Can flow over into painting and writing so watch out.

Chess is even cheaper (free online with matchmaking: lichess.org also a gazillion youtubes to get you running like chessbrahs or chesswibes) if you want to be humbled but also like tactics, strategies and history.

I did Taekwondo at one point in my life. It was super fun, because I actually felt like I achieved something (a belt) for my hard work

Video games might not sound like much of a change, but they’re more active than watching movies. It’s a small step away from that totally passive mode.

Origami I find fun, yes.

Have tried to learn to juggle several times, unsuccessfully.

Doing yoga I have learned to stand on my hands, learning a physical skill like acrobatics is so good for both mind and body.

Live music I love so much. Go see a show!

I guess it's a game too but Pokemon go has actually gained me some casual friends.

I've not been able to do any of these for a while with life doing its thing and being overwhelming, but I've enjoyed things like those "gem" mosaic pictures (apparently called diamond painting) and good old colouring books. I also got in to making stim jars for a while, then someone suggested I monetise them and I completely lost interest lol (though that gif is making me want one now)
Also tried indoor gardening for a while, but I just kill any plant that comes my way, so I've stopped that abuse now😂

One could argue that a boring life is the best one could wish for. Perfect time to make some kids. That's natures way to cope with that situation. :)
