That's the problem with learning chess, or anything that takes a good amount of experience to have any kind of success. If you knew how to analyze your mistakes, you wouldn't be making them in the first place. The best advice I can give you is to look at a move you want to make and then before doing it, see if 1. Will it be taken? 2. If I move it, what protection does it have? 3. What protection was it giving in the old position? 4. And while doing all of that you look and see 1. What is the other guy giving me? Hung piece? Take it, as long as it isn't a sacrifice. and most important 2. What is the other guy going to do and where am I the weakest?

Once you know which mistakes you are making, you should practice whatever you did wrong. Lost a won rook endgame? Study them, find what you did wrong, and next time you might win. Blundering forks? Do fork puzzles until you can't not see one. Of course the talking part is a lot easier than the doing one, however, because I still blunder simple tactics all the time.

If you are serious about improving, you will find it helpful to study what was the cause. Did you finish development before beginning your attack? Did you have sufficient material for the attack? Did you commit a blunder and lost a major piece? Were you in a bad position from the get go and never had the initiative?
You don’t need to memorize the main lines of various openings, or discover brilliant traps that win games quickly. Maybe you can add those things to your repertoire, but as a beginner or intermediate you should just focus on basics and fundamentals.
Do you have a list of principles to follow during development? General guidelines like don’t make pawn excessive pawns (ideally only move a pawn unless it’s to develop a piece - uniquely, pawns can not return to their position, and going forward weakens the squares on either side.) Knights before bishops. Fight for the four squares in the center (d4, e4 d5, e5.) Castle before move 10 if your pawn structure allows it.
When possible, keep pawns beside other pawns or connected on a diagonal pawn chains.
Make sure your pieces are well placed to control squares and serve a purpose. Knights control more squares when they are placed within the 16 squares between the c and the f files and the 3rd and the 6th rank. Bishops closer to the edge control more squares, slicing across the board. Rooks belong on open files (no pawns of either color) or semi-open files (pawns of only one color.)
King safety is paramount. Always scan the board to see if 1) your king is safe, 2) your opponents king is vulnerable.
A/B system: AFTER your opponent’s move, what is their plan? What are they attacking or preparing to attack? BEFORE you move, check blunders - are any of your pieces hanging / undefeated? Is the move you are contemplating susceptible to capture?
I add a third & call it ABC - check the clock, are you ahead or behind your opponent? Not something to fret about but always have at least a vague idea if you are managing your time well or need to speed up.
Slow. Down. When you see a check, capture or attack, don’t impulsively make the move. Are you setting yourself up for a fork or a pin? Is your opponent using a deflection tactic to get you to move a piece that is controlling a square, file or diagonal they want?
Thats a lot, but when you develop systems and habits, you will learn how to do
It quickly - and with confidence.
