Elubas, if you work earnestly and play tournaments frequently, and are not bothered by losses, your rating will improve. Fast.
Care about the games, but don't be bothered by losing them, study hard, and you will get there. Experts and Masters suck. Trust me.
...LESS losses bother you, the higher the level you can reach.
Profound words.
True. Things might get paradoxical though if you use this as a strategy to get better
Because if you end up not getting bothered at the loss, and your rating doesn't improve, then you will end up getting bothered by the loss after all because the strategy didn't work.
So I think a better approach is to simply be happy anytime you learn more about the game, with rating improvements merely a (very cool) bonus. Every new thing you learn should feel like, I don't know, Edison creating a working light bulb :p
