I'm thinking about stopping playing chess

Ur not gonna improve playing blitz.

I mean if you are playing for tactics and to push pawns and harass pieces, you can go up in rating points in blitz quite rapidly despite playing like a headless chicken.

If you take time out to learn from masters or a book and are now starting to think in a different way when you view a position like "how do I stop him from playing c5" - well this is no good in a blitz game, it's all about just harassing and pushing and forking, etc. Thinking about those subtleties in a blitz game at lower levels is going to be a waste of time because you have bigger issues to worry about and much easier ways to get the upper hand.

Also, you should always play with increment to avoid nonsense at the end of the game. Always play with increment.

Yeah, if u just have to play blitz, use increment at least.

Ultimately, it's personal thing. Does chess stands in the way of your main profession or personal obligations. If it is something so much more interesting, rewarding, relaxing and satisfying, than even that you could not do all the time, even if you are filthy rich. Second, are you maybe some engineer, scientist or programmer, again, it's something, where you again must feel disturbed and without inner peace from the time to time. Are you maybe an artist, for whose sake you have to prove yourself? You know you are good and worthy and you don't give a damn about approval seeking. Ultimately, the most balanced and rewarding satisfaction is this game on whichever level you are at. You mentioned the age of that chess masters, that disappointments are not because of the game but phaze of the life when the young man feels the most disappointed and disturbed. Eventually, you will be back to the game with fresh view upon yourself and renewed and even bigger inner peace resulted from knowing thyself.

Chess is a just a hobby, so take it easy. Take a break from it if you think it doesn't bring you any more happiness. Or, stay involved with chess in different ways. Try some chess variants perhaps. Warning, bughouse is damn fun and can be addictive. How about join some local chess clubs? I see folks go to these clubs to socialise over chess. You may make new friends and even your soul-, eh, chess-mate at these clubs. Why not organize some chess community events? You don't need to be a grandmaster at chess to show others how fun the game is. Some of my local chess club / community founders are not even strong, but they are well known and respected by the players because of their passion and contribution to the community.
A quick Google search for chess community in Singapore yields this very interesting community https://www.instagram.com/aliwalchessclub/. Maybe I can give them a try on their next event.

100 PERCENT CORRECT.

Try to watch Computer Chess Championship... Try to predict all of the moves of one of the engines...

Try to Solve Chess.com And Lichess puzzles

After You solved some 10 or 15 Puzzles...

Play the games it will make u concentrate even more.

Strange but true. Exactly that. No more than 10-13 puzzles and you're back into the flow. Why is that I don't know but it works.

Instead of focusing solely on your rating, set realistic and achievable goals for yourself.

Same here. My consequence is to take a rest and maybe do some puzzles and some games against the computer each day until I gain confidence again.

I dont know how but after i Solved my coachs Puzzle I Was Able to draw with a 1700 or 1800 I Dont Remember but i managed to draw .

And i kinda Destroyed a Guy IN Bullet With a Rating 1900 I Think That is Fake Because He Was Playing like a 1000ner. I Easily Beat Him

The Player - * *

I Am Trying to Beat Wally Bot In The Month of March Thats MY Goal For the month of March

not exactly, I said that I usually play at a pace of 5 minutes and after dropping from 1300 rating to a rating below 1100, even taking sound classes with a master, even training tactics and they told me that before playing, do 20 minutes of lessons tactic I use in chesstempo and still lose. that's what he said

Maybe not, I've already beaten players with 1800 rating, that's the pace I'm used to, so it shouldn't be a problem
