Could it just be something temporary?

I remember that up until before I turned 20, games were my life, my passion. There wasn’t a Nintendo cartridge or a PlayStation CD that I didn’t have. I always had a lot of video games at home. I collected walkthrough magazines, etc.
But after that, I don’t know
it feels like when you enter adulthood, all of that kind of gets left behind, right?
I’ve already bought lots of games that I never even opened, and when I do open them, I already jump to another one and never go back to it. At the first boss I die to, I just close everything. I don’t put in any effort anymore. I can’t even handle watching 5 minutes of a stream. Everything bores me. Is this feeling normal? Does it happen to you too?
