Feynman's endgame book

Complete course to endgames or something like that

The book 100 Endgames You Must Know by Jesus de la Villa is excellent

I learned endgames with that book (Feynman) and youtube but I am not the best at them either tbh

Have you done the endgame lessons on chess.com?

Ruben Fines Basic Chess Endings.

it is dry, boring, and technical but it will teach you what you need to know.

Learn the basics and intermediates of endgames. Once you know what can win in the ending you will have a much better idea of what to play for in the middle game. One time in an OTB tournament in round one I was playing against somebody about 600 points weaker and he said he though he did quite well staying materially even until around move 30. I told him that may have been true but he lost it on move six when he let me give him doubled pawns on h2 and h3 which was a permanent endgame weakness, at which point I simply traded everything off to go to the endgame. To avoid that simple loss he tried counterplay that gave me a material advantage but if he hadn't then I still had a simple king and pawns win even with material equality.

Sure.
Lets help the original poster - with endgame comments and insights.

First - endgames might seem more positional than tactical - but that's a misconception.
If tactics aren't understood or appreciated - then endgame skill is unlikely to improve.

Second - you'd find there's controversy about where the endgame begins or what defines an endgame.

Third - why do so many people have more proficiency in the middlegame than in the endgame?
One of the reasons is that in endgames - material advantage is emphasized.
Which means exchanging down is often useful or necessary to win.
Simplification. Attrition.
There's a saying 'Don't exchange down without a reason'.
But there's a counter-saying 'Don't choose to not exchange down - without a reason.'
Persons averse to exchanging down are going to have more trouble in the endgame.

4) in time-control chess - the faster the controls or the more the game has progressed to time scrambles - then the more endgame play will be rushed.
Which means endgame experience and consideration and development gets squashed with that.

Okay - that's four so far. There's more - like the business of pawn promotion is kind of absent from openings and usually middlegames too ...

#4 above brings up a very good point.

you do not learn endgames while playing.

you study endgames and then while you are playing you identify and then apply them.

Well that's part of it then.
An idea would be to consider contrast of endgames with middlegames.
Think about it. First. Before studying or memorizing.
5) openings and middlegames don't address pawn promotion and its intricacies much.
6) In openings and middlegames - zugzwang doesn't usually come in.
7) Nor does stalemate.
8) In endgames it often or usually gets safe for both Kings to come out from behind their pawns. The Kings and their attacking and controlling and central power don't usually come into play in openings and middlegames (are targets instead).
So its Different.
Being more aware of the differences could help with surmounting them.
