Analyze your games and learn from them.
how to improve my elo?

It would be nice if there were an ELO opt-out, for beginners.
If you're on here, then you'd probably wipe the floor with the majority of people, if they played chess against you. The reason being, most people learn the rules of chess at some point in their lives, and maybe play a game when they're with relatives at Christmas or something, but other than that they go for years at a time without playing.
Not sure why everyone's automatically opted into ELO anyway. It's a number, and it's based on averages of people who are enthusiastic chess players. Enthusiastic chess players shouldn't be compared with us, but with other enthusiastic chess players. I call them enthusiasts, but really they're more like "serious students of chess". If you've got a book or you study something by another means, then you're a student of that subject.
The reason I think this number causes hangups is, for us beginners, it's like a roll of the dice, when we play chess. On the L site I played a lot, choosing opponents based on being curious about their username. I never got much better just by playing random people, but isn't that what chess is supposed to be about? A game played for fun and curiosity. I only started doing puzzles a couple of days ago. That's the first time in my life I've ever done a chess puzzle. Also, I've never read a book or watched a tutorial about chess tactics. So, obviously I will be way lower than 1500 ELO. That's so obvious - no reminder needed.
Most sites and chess computers treat everyone as if they're on a ladder. This is one of the main reasons, I believe, why big ego people (e.g. billionaires, famous mathematicians and scientists) avoid playing chess. They're scared of having a low number. The ELO system is absurd when it comes to us beginners. I've never stepped foot in a chess club, and don't know anyone in real life who plays chess. Being forced to have an ELO rating is like riding a bicycle that's permanently uploading your "performance" to Strava, whether you like it or not.

If you do enough puzzles they will create themselves in time
And you'll learn to look for ways to set up positions with the same idea as in the puzzles if you see the opertunity in the game
You won't learn how to set up positions without doing puzzles

Literally everything about this comment is outrageously wrong lol.
First of all, the majority of chess.com users aren't chess enthusiasts and would not wipe the floor with the average person, let alone the majority of people. In fact, the average chess.com user is only a tad bit better than the average Joe off the street, as evidenced by the median Rapid rating on the site being around 700. The type of chess player that you describe in the second sentence of your second paragraph is the type of chess player that most, or at least a large minority of, chess.com users are.
Secondly, you're signed into the Glicko rating system by default because it is an excellent tool in providing competitive match-ups. Without it, precisely what you're complaining about would happen, and beginners would get matched up with stronger players, and hence get hopelessly crushed, a good chunk of the time, making for a pretty poor playing experience. The games are Glicko-rated by default PRECISELY because "enthusiastic chess players shouldn't be compared with us, but with other enthusiastic chess players".
Thirdly, no, you won't "obviously be way lower than 1500 ELO" if you've never watched a chess tutorial, read a chess book, or done a lot of tactics. I've never done any of those things myself, and as you can see, I'm way above 1500 both on this site and OTB (which is what the term "Elo rating" is usually used to refer to, by the way).
Fourthly, far from all billionaires, much less great mathematicians and scientists, have big egos. Your belief that they do is what we in the industry call "copium". Stop being jealous. Just because they're more successful than you will ever be doesn't mean they have big egos.
Fifthly, no, ego doesn't have anything to do with it: a lot of people don't play chess simply because they don't find it fun. Yeah, believe it or not, not everybody shares all of your interests. If anything, chess seems to be a bigger hit in mathematician and scientist circles than in the general population, so even your premise that billionaires, mathematicians, and scientists don't play chess is confusing and, frankly, wrong.
Sixthly, you can always switch on focus mode to hide both your and your opponent's rating, or simply play unrated games if you so wish. Literally nobody is forcing you into Glicko, so I don't know why you're complaining. Moreover, I would imagine that most beginners (like me 2 years ago) would find Glicko to be a useful tool for tracking progress (in my case, I found it invaluable, and it was one of the biggest reasons I kept playing chess for so long), so it makes a lot of sense to keep it as a default.
Phew, that was a handful.

Thanks! I always appreciate the input of an autist. I mean, really.
I don't want to point out that you don't understand statistics and data, and as such don't have the Glickaustist rating of my grandmother or uncle on this site. That would contradict, and offend, your great highness. Thank you for pointing out I'm wrong in knowing whip Nassim Taleb's ass in a game of chess.
So yeah, I accept my correction.

If I'm breaking the rules by pointing out I would whip billionaires like Elon Musk and mathematicians like Taleb into a fine paste in a game of chess, then don't count on my continued business... These guys have huge egos but would lose to a low-ELO-rated player.

Hi! No shortcuts really, there are so many things to learn in chess that it takes a lot of time and effort. If you wish to improve faster you sould consider working with a teacher/coach. This will save you a lot of time. I'm a Chess.com coach and I'm have some time available, please check my profile and if interested in lessons and coaching send me a message for details.
Good luck!

I doubt if you're breaking any rules by talking about billionaires. It's more likely that an over-zealous algorithm picked up your use of the a-word - i.e. the a-word that is a synonym for backside (I myself have mostly recovered from the shock of seeing the a-word on the screen, but others may not be as thick-skinned as me)
It's also possible that someone complained about your autism reference.

Here’s more ideas to help you get better.
-I recommend two books for you: “50 Poison Pieces” and “Queen For A Day: The Girl’s Guide To Chess Mastery.” Both books are available on Amazon.com. Both books are endorsed by chess masters!
- Check out the 500 puzzles for beginners. These puzzles are unique and cannot be found anywhere else: . These puzzles are endorsed by chess masters!
-If you are serious about chess, I highly recommend you hiring a chess coach to help you.
-Also consider all checks and captures on your side and also your opponent’s side. Always as, “If I move here, where is my opponent going to move?”. Do this for every single move!
-Play with a slow time control, such as G/30 so you have plenty of time to think before every move.
My chess.com's elo hasn't improved for one month.Is there any shortcut on the way to become stronger?
