I can't help but wonder if I might plateau as some of my opponents have. I would imagine that even a leisure player with a desire to improve would still gradually show some progress over several months of thoughtful play, game reviews, honestly doing problems (no peeking at the answers until you're 100% certain you got it right) and all that sort of interesting study.
But I also thought I read somewhere that there are certain rank-related barriers where a lot of players do plateau. Are these real? If they are, what makes one break through? What makes one languish?
Sorry about all the questions today. I think I'm just in some befuddled state of mind.
