How to anaylise games

Im in a constant cycle of winning a few lucky games and then losing dozens more. I dont know how else to grow my knowledge or improve.

I'm a little confused looking at your games. You seem to resign a lot. Even in games where you have a decent of rven winning position. You have plenty of time according to the clock. Are you resigning because you think the positions are bad?

Keep practicing

I like to study my chess openings to get a better understanding of the position. But when you analyze your games, you need to find where you went wrong. If you were losing in the opening, you need to find the best continuation so you don't make the same mistake again. If it was the middlegame, find the tactic you missed. If it is the endgame, find the best strategy for the position. 

Hello, I can analyze some of your games, fully commented.

Just contact me privately, greetings.

When you lose a game, stop playing and analyse it. You lost the game, so you made at least one mistake. Go to the final position where you lost. Then peel back move by move until you find a better move that does not lose. Did you consider that move? Why did you play the mistake? What other moves did you consider? How much time did you think before you played the mistake? How much time did you have available on your clock then?

Yes, usually after I make a move or I dont expect something I get demotivated or frustrated if its a really dumb mistake.

I dont know that during the game, and post analysis i still dont know that because i dont know what I am looking at half the time.

At the beginner level you shouldn't give up, even if you think it's losing. You never know what your opponent could do. For example in the game below i was losing bad. But one mistake won me the game. https://chess.com/live/game/15788152243

Chessvibes is a lesser-known channel but with some great content. In the below video Lopez gives a method that is different to Gothamchess but very valuable in my opinion:

It is ok to not know where you stand. The problem is RESIGNING. Im not going to say you should never resign, but you probably should not resign unless you actually can visualize the forced moves that will end with you being checkmated. 

Don't resign. Even if it's frustrating. Let your opponents show you how to mate. You'll get better at defending and chances are your opponents make mistakes later on.
