Help with getting good in chess.

May be obvious but you should analyse your games, even the ones you lost. Go through it without engine m, go through your thought process of the time and see if you maybe had anything better. Or if you missed any tactics, ask yourself why you missed it and how to recognise it in the future. Or go through your opening prep, did it match what happened in the game and you can Gradually improve your opening.

Maybe you could also try some blindfold training for visualisation, get a training partner, and look at the board every 4 moves while playing a game. Eventually you will get to 5, 6, 7 and so on.

It’s also useful to do tactics, obviously. It doesn’t matter if you spend an hour on the puzzle, try to calculate your guts out because it’s good training.

Openings are a good thing to study as well, also studying the middle games that arise from it.

GM games are also useful to look at, especially when you are studying an opening, you can see how the GM handles it and the middlegame that comes from it. 
Books and courses are also useful.

Silmans endgame course is a very useful theoretical endgame book.

Reasses your chess is a book is about middlegame and strategical play.

Coursea are also useful if you want to learn an opening. 
If you are willing to spend money, chess books and courses can be a good investment. But make sure you are getting the right ones for you.

also, just spending time on chess itself is useful. Looking at chess broadcasts, watching your favourite chess streamer, even playing a lot of blitz games is useful to your chess

So basically:

1) Checks, captures and attacks (for both players)

2) Puzzles (Lichess)

3) Main Openings (2 for each colour maybe)

4) Master Game Analysis

5) Avoid learning traps

6) DON'T OVERDO IT

Maybe like Gotham says and I try to use the ideas too: look for checks captures and attacks that you can make and that your opponent can as well. Also I feel like the most accurate move for my opponent would be one that activates the major/minor pieces in a way that i scrucial to their plan or just a hinderance for me (eg: controlling open files) or maybe a checkmate threat. Puzzles are a great way to look for mates in 1 or more, if you don't have a membership maybe use Lichess? My friends say that it has free infinite puzzles. But do like 15 puzzles max per day and spend like 5 mins straight on just one if you have to; if you get it wrong learn the idea behind it. If you are winning more games with 1.e4 just continue studying on that: learn the how to comeback to the sicilian, the french defense, the scandinavian, the vienna (use opening tree - great resource http://www.chesstree.net/). And pick one or two main first moves for both colours and then expand and learn as many variations or sidelines. Eg: If I choose 1.e4 I try to learn the sicilian, the french defense, the scandinavian, the vienna, etc and same goes for black. Study master games and maybe even hire a chess coach. But NEVER try to learn a trick like the Fool's Mate or stuff like that cause there are so many variables and if one doesn't work out the rest of the game might be miserable for you. (MAKE SURE NOT TO OVERDO THE PRACTICE)

I'm 2350 chess.com and in OTB (over-the-board) tournament play have won a few provincial championships in Canada.

My best advice:

1) Play. Study becomes an unrewarding grind without play. Play slow games for improvement, quicker games for fun.

2) Examine your losses. It's unpleasant focusing on your defeats, but each lost game is a gold-mine of information. Study each one, and don't give up until you know why you lost it. If you could learn one useful lesson from each loss, you would be a 2000+ player in less than a year.

3) Focus on tactics, model mates (also called checkmating patterns), Pawn structure and endgames. Not simple endgames like K+R vs K, but harder stuff like K+R+P vs K+R.

4) Read this thread, and play over the example games. The first two or three pages should be enough.
