This is where your worldview is skewed.... Try finding worth in the things that improve your life, lifestyle and the people around you. What you just described is a miserable and selfish way to look at life.
You keep saying people have to "grind" and "focus" and "work" and "dedicate" to get good at this game...
I didn't start playing video games as a kid to be the very best at all of them... I started playing them as a fun way to interact with other people and to achieve a level of escapism that you can't get in reality. ( Like most of us)
Beyond that, when you start to warp that motivation into something different, like "grinding" to get gear... you sir have an addiction to something that isn't rooted in satisfying anybody else, but your own addiction.
It's miserable, and you'll never understand the freedom it brings to just play a game to have fun.
When I grasped this... I improved across the board in all of the "competitive" games that I played.
I hate seeing people literally psychologically and clinically depressed and addicted due to a video game... It's sad and breaks me...
