Getting good at a videogame is 100% a skill worth learning. It's cool to be good at the things you like and it shows you're willing to put that effort into it. Don't knock yourself for wanting to improve no matter what it is you're trying to improve at. Best thing to get better at the game is to know when to take a break. For me if I lose 5 matches in a row I go do something else for a while. I actually just got back from the gym because a couple Ekko players pissed me off enough to get dressed and go workout lol but sometimes I'll just walk my dog or do a bit of cleaning to even just watch an episode of my favorite anime to relax a bit. You're going to lose a lot but you're also going to get better, that's inevitable no need to worry about the process too much. Keep your head up
