Any tips/suggestions to improve?

Get a chess coach for the fastest improvement, if you can afford it.

Otherwise you're sort of trying hard but may not see your weaknesses, and may be focusing on what pleases you more than what is best. Like trying to memorize opening moves but not fully understanding why the moves are good moves.

@lance5500 is a great coach, but if that's not your cup of tea, the coaches page has many.

Good luck!

For books, maybe look at Coach Yourself, Training for the Tournament Player, and Chess Training For Budding Champions. Build Your Chess series is great, as is the Steps series.

Ultimately it is hard work that helps most. There's no shortcuts.

Edit: and it will take a very long time to get very strong, so enjoy the ride :)

15. When behind, exchange pawns. When ahead, exchange pieces.

What does it mean please? behind = losing ; ahead = winning?

Get a “chess tactics pro” app on your phone and solve the 250 free puzzles, then do them all again. And again. If you pay a few dollars they have 3000 puzzles. Another phone option is CT art, they have apps for beginners with tactics and lessons on strategy etc.

For a book Polgar’s World champions guide to chess is a good start. After that you can do a Silman book like Ameteurs mind or Reassess your chess.

Basically solve thousands of puzzles many times over, and read a few books, that alone takes you to 2100 and above.

Structure your chess training around solving as many tactical/strategic puzzles over the board as you can. If you're planning on playing in a real tournament it is very important to do most of your work on a real board. You will make mistakes on a 3D board that you normally wouldn't on a 2D board, being that you only train online. GM Naroditsky gave good advice in a video he did years ago: Play only a couple games online a day! I wholeheartedly agree with this advice even though I don't follow it. My biggest chess gains have been during times where my online playing is limited and OTB training games with partners of like-strength are frequent. Also, if you're super serious about improving, start slow. Don't burn yourself out with some Kamsky-father-son-like eight-hour training regimen. I'd recommend solving tactics for an hour, play a couple games online, preferably over 10 minutes and with an increment. If you love playing 5 minute games, I'm not going to tell you to stop. The key ingredient in the recipe for NOT burning out, is to enjoy yourself. Then do an hour of endgame training. I'd recommend playing through the examples in Mikhail Shereshevsky's Endgame Strategy, on a real chess board. As for problem solving, too many solid recommendations to name. Zenon Franco's 1001 Puzzles comes to mind, get in on Kindle for cheap! Happy hunting.

Ignore all the advice, however good it is or may be.
If you want to improve, play, play, play and then play some more, if you get battered by an opponent check the analysis on Lichess.
Very few people will ever reach GM, so just be patient, play, play and play some more and when you get beaten by a lower rated player analize your game.
If you really want to get to 1900+, then by all means, get a coach, read books, study games and spend 4 hours a day playing, but if you simply want to improve then just PLAY as much as you can - all depends on your actual goal, do you want to improve or do you want to be a GM/IM/CM etc?
