Many of these things I don't understand how they are hobbies. Mechanical keyboards for example. I bought one, now I have one. That's it. I love coffee, I drink it daily. But that's not a hobby. I got a gaming PC, I game on it. And that's it. I have a couple house plants, I water them sometimes. Done. I built a server with all the Arrs and Plex, and it's awesome. But now it's almost fully self sufficient, that hobby lasted about a week.
