Well, I can’t help you with this, it’s to do with your genetics, attitudes and even upbringing
It does feel weird to me, though, that you don’t consider all this typing on the forum ABOUT the game a waste of time, while at the same time you consider PLAYING that same game a waste of time xD
I can’t understand that xD I can just assume it’s a product of strict, conservative upbringing which kept teaching you that playing games is a waste of time.
Well, if that’s true, I might be able to help you. I, too, felt guilty conscience while playing games instead of doing something productive (studying, working, hanging out). But then I grew up and realized everyone needs some “off” time, to wind down and fill themselves with dopamine. Sometimes that means watching TV/movies, sometimes it means playing games, sometimes it means something else.
But having fun and keeping your braincells working definitely isn’t a waste of time from my point of view. It’s quite important. So important, in fact, that I will sacrifice sleep for it and still be productive on my work, because the game playing filled me with more dopamine than 4-5-6 hours of sleep ever could.
I do, however, understand that not everyone can do this. Some people need more than 8 hours of sleep because their organisms is more physically oriented than mentally (they waste more energy with physical activity than mental), so they literally need it.
It looks like you might be one of those “physical” types. Are you going to the gym or doing some sports?
EDIT: I have another question for you, but it’s a long shot and I prolly shouldn’t ask it as I’m not a doctor, but I’ll do it anyway. This part of your reply:
reminds me of my best friend’s issues (brain fog, tiring easily, prefers physical over mental), and he has Hashimoto diagnosis (autoimmune thyroid disorder).
Do you also happen to have some thyroid diagnosis? It could explain the brain fog and tiring quickly.
