how to improve, or just quiting.

Well, this topic has been covered hundreds of time, 

but can online chess really help to improve? To me it is just utter frustration, and I can't break my routine. 

I can never succeed in thinking about a position any longer than 30 seconds. It just does not work.

The computer analyses and most of the videos are just causing more frustration as they often seem beyond beginners levels.

I watch a lot of youtube stuff, and always it seems so simple but when playing chess myself it just does not work.

Is it possible to break such a routine? 

yep .. slow down

Just accept the fact that you love to play fast and play time controls suited to that desire.

I started as bullet player. Transition from 1 min to longer time controls is long and paintfull with a lot of loses due fast move. More than six month since i decided to play a games longer than 1-3 min and i still play better at bullet. I need more months to fully recover from bullet addict.

You have to change your entire approach if you expect to improve:

1) Study Books, and use a board, not Artificial Intelligence.  The fact that you have to physically move the pieces yourself rather than clicks, drags, and drops actually makes a difference.

2) Go to Over the Board tournaments with long time controls

3) Before you make a move, look for ALL candidates, no matter how absurd they may seem.

4) Always consider forcing moves first.  Maybe Rxg7+, throwing away a Rook, actually wins the game!

5) When you think you have the answer, look again before you actually move.  Don't just look for alternative moves for yourself, consider alternative possibilities for your opponent besides the obvious.  In-Between moves are commonly missed at the amateur level!

6) Continue to play Correspondence (or Online, as they call it here), and limit yourself to 10 games max at a time with nothing faster than 3-days time control.  If there is an opening you wanted to learn, use it here in Online Chess before you try to use it over the board.  Who the hell cares about online ratings at chess.com?  Your over the board rating is what truly determines your strength!  I'm 1800 blitz and 2000 Online here, 2161 over the board.  Shows you what little I care about chess.com ratings.  They mean nothing!

no, online chess won't help if you only look at the board for a few seconds.

Try treating the game as a daily puzzle and looking for "the answer" from that angle of forcing something or scoring a piece etc.   Take your 30 second look, write down the move you picked, and step away for an hour or two.  Look again, repeat for a day or two... just never make the move.  Flip the board, look at it as if you were your opponent.   See if anything like that helps... 

chess.com ratings means everything. Is recpected more than any other chess site. #1 place for chess with huge amount of players online which is  true strength scale. Everybody is playing here for rating. Ofcourse small portion plays only for fun or does not care about online chess at all. Otb fide rated players usually have simular or lower rating than their chesscom rating.

So saying you are 2100+ otb and only 1800 in blitz means you lie or is not fide rating or you are really bad at blitz or you dont play otb for years and got worst , i cant agree you dont care becouse you max is 1864 and tactics 1860~.

I think you are being to hard on yourself.

I think you are putting pressure on yourself for no reason at all.

Sometimes people don't improve simply because of the stress they put on themselves.

Sometimes the best way forward is to take a step backward's.

Take a step back to observe how far you have come.

Check out the below game you played.

Now you might try and flip out on me and say its a terrible example!

However, It is a perfect example.

The simple fact is everyone loses in chess!

Every World Champion was once a beginner and every beginner has lost games!

You can say you lost in 9 moves all you want too.

However, you can not prevent losses in chess.

All you can do is learn from them!

Even chess engines lose against other chess engines!

Look at the first 4 moves of your game!

Those moves right there are text book moves.

Grand Masters & World Champions have reached such a position!

"The computer analyses and most of the videos are just causing more frustration..."

Well I disagree with you.

You reached a position Grand masters have reached how on earth did you get there?

It is obvious the analysis your doing and the videos you are watching are helping achieve something great!

Maybe the problem you have is you simply need to go further with your analysis!

The move 5...d5 is not the most common move for black in the above position!

Black has several options in this position.

The move 5...d6 supporting the bishop on c5.

or

The move 5...a6 giving the bishop on c5 a nice little hiding square.

or

The move 5...0-0 getting the black king to safety behind his nice pawn's.

2161 over the board means with over 1 000 games online blitz, even if you dont care,  your best victory should be 100% at one point at least above 1860 rated player which is not the case. Blitz  can mean 5+3 or 10 min game where hanging pieces are rare and only at very end for 2k rated player.

Actually I believe parts of what ThrillerFan is saying is true and other parts are lies.

I do believe ThrillerFan has a ranking of 2100+ OTB.

I believe that part is true.

However, the part I think he is lieing on is the chess.com ranking part!

I believe the ranking ThrillerFan has on chess.com is very close to accurate.

From a math perspective chess.com rankings should be lower in comparision to OTB rankings.

The reason why is because of the player pools.

There are more active players online than OTB.

Which means more competition.

So the rankings on chess.com should theoritically be lower than OTB rankings.

The only time this assumption is wrong is when you get into the extreme ends of the spectrum!

Like the top elite!

Like the extreme end of the player pools.

Someone like Magnus is number 1 and is winning OTB.

If he played online here his ranking would shoot higher than his OTB ranking because he has more player points to feed off of bascially.

Which is why you see people like Nakamura in the 3k's.

For most of the normal players here that isn't the case.

A friend is 1900 fide o4b and 2200+ blitz here. Title players NM or CM are close or way above 2200 blitz. There are some exceptions, veterans, people who quit otb chess with high otb rating but they play online with skills far lower than what they were otb. If i am 1800 here, does that mean im 2000 over the board? Ofcourse not. 

Well I know some people who are 2000+ OTB and are only 1800+ here.

Which is to say you can't say it is not possible!

@AIM-AceMove

I will also mention you are forgetting about cheaters effect on player pools!

Obviously ThrillerFan could possible reach 2100 online if there was no cheaters.

However, the sad fact is cheaters do exist which means it will effect his earnings whether you wish to believe it or not.

Which is why the ranking 1800 could be accurate!
