For me it was probably CSGO. I started playing at like 15-16 and while I really enjoyed it, I also found it really frustrating. Some of my highest highs and lowest lows were in the game lol. I would get really mad at the game and my teammates.
I stopped playing around 2018 and picked it back up a couple weeks ago with all the CS2 news going around and now I don't really rage or anything. It's just fun and when I lose I don't really care. I think I just matured and playing it casually without caring about my rank has definitely helped.
I would love for that to be a thing!
I agree that it should be done in this community instead of creating a new one. If you need any help with anything, please let me know as I would be glad to help
