If I had a group of people to game with, I'd be doing that. Unfortunately, in the past 25 years there's only been two people I've managed to game with for a couple weeks and that was one on one - no group. Neither person ultimately meshed with my outlook and style. And by 'game with' I mean, sit down crack open the books, pencils, character sheets and dice for an RPG, with one person being the GameMaster/DungeonMaster. So mostly, I'm just on my computer doing my own thing that's aligned with that stuff (mainly writing).
I'm a product of how I was raised. My father was relentless in trying to make sure that every second of my weekends were filled with labor. Of course, he had free labor in me, so there I was cleaning the pool, mowing the lawn, trimming trees, etc. More than once he also put my friends to work, who'd been invited over to have a good time and were not expecting to be put to work trimming trees or mowing lawns.
So, I learned to resent work unless I am being paid for it. And I am happy when I have nothing to do or am doing something I want to do. Lots of people would consider me a very big time waster, but I don't care. It's my time and if I just want to bang around on the internet or whatever…well, I'm an adult. I can do that and no one (especially my dad now) can tell me I can't.
I have a home, I've been married 25+ years to the same person and I have two kids. I have a job and with my wife's job it pays our bills. I work hard, I'm loyal to my wife, the bills are paid, need are met. So if I want to 'waste time' on my time, I will. Being 'productive', to me, is highly overrated. Being 'productive' is usually pushed by people who can't stand to be idle for even one second and who must, for some reason, make sure no else is idle. My dad was that way.
I don't watch streamers on YT. I watch videos of people who've already played through a game and recorded it, then posted it on YT. I don't want commentary or anything else. I just want to watch a game being played through - especially if I've never seen it before.
As to music, I'm a big fan of Celtic/Gaelic music and it's offshoots, as well as ambient music. I'm a heavy user of the Dronezone channel on SOMA FM.
