I already commented on your older post so I'll just copy-paste what I wrote:

Let me tell you, if your interests keep changing and you’re easily bored, you’ll get bored of every new hobby you find. Thing is, boredom is inevitable even when we do things that are pleasurable, so you might as well find something you actually like and “elevate” yourself in some way (be it physical, intellectual, emotional, spiritual, you name it).

I’m a psychology student and I love what I study. Is is fun? No. Do I get bored often? Hell yeah. But god I love doing it, because at the end of the day I feel enriched and with a new perspective on the world. Every single time I decide to persevere through difficult or boring material instead of booting up a game or watching YouTube I feel so much more myself.

And mind you, I’m terrible at this. I struggle so much to keep myself from getting into the hyperstimulation rabbit-hole, and I often spend whole afternoons jumping from one thing to the other (not necessarly games/social media, often I keep jumping between books and articles and projects every 10 minutes without ever finishing anything), but it’s a process.

That said, I would suggest someting like music production. You can get as wild as you want with technicalities but it’s also creative. I recently discovered Pure Data and it scratched that itch of both doing something creative and learning something technical.

Whatever you choose, embrace the boredom! It’s part of everyone, it’s part of life. The hardest thing is getting started (e.g. I stayed up late to work on a new hobby and the next day I have no desire to get back to it, but as soon as I start doing it again for as long as ten minutes I’m absorbed again), often you’ll fail but it’s not a race. You could also get back to an hobby you started a while back but approach it from a different perspective (for me Pure Data did it with music production and coding), so that you’re not overwhelmed but don’t have that feeling of “already seen” neither.

On a side note, mandatory “are you seeking professional help” question. If you’re not, start doing it. If you already are, good job! It can feel slow at times, maybe you keep talking about the same thing (or change topic everytime) and feel like you’re not making progress, but it will yield its result in the long run!

Good luck with everything man! I know you’ll get something out of this situation :)
