Its definitely a mindset thing. In any game with any sort of competition, the majority of people seem to have this thought that “I must win”. And if they dont, then they are having a bad time.
I notice this alot in smash specifically when I play with new players, they put all this emotion into matches with nothing on the line. Then beat themselves over every loss.
I even get questions like “Why you did this dumb thing?” which sometimes leads them to thinking im trolling. Like bro, im playing for fun.
Or if im not sweating 24/7, “Are you sandbagging?” Dude, we are playing friendlies, this is not a tourney that decides my future career, its not that serious.
Its like people forgot what casual gaming was.
I had a similar issue and honestly I would just recommend worrying about it later. Don’t force it, just try it when you have some free time.
I started off with dual boot to play with Linux and jump to windows when I need it. Then eventually to full Linux once I realized I never actually needed it to do all my work.
I recommend Linux mint as its the most similar to windows and is built for new Linux users. I tried Ubuntu first and the experience was pretty bad, but I learned much quicker in mint and had a much better experience right away.
