i look at game collections no capablaca 60 best chess endings.

I stopped playing blitz

What else can i do.

Kotov's Think Like a Grandmaster.  It's an excellent book as it's written in a conversational style and covers the basic elements of chess: calculation (especially as the book is most noted for this part), positional assessment, strategy, and the endgame.  It's a very basic coverage of all these parts but they're a great foundation.  The endgame part mentions schematic thinking, not hurrying, and bring the king closer to the center when you have the chance.  Shereshevsky's Endgame Strategy goes into more depth on the issue. 

By "great endgame knowledge" I'm assuming you mean relative to your skill (e.g., when someone says xyz grandmaster sucks at the endgame he's still better than nearly everyone at it objectively, but is worse than his peers such as Nakamura playing the endgame at IM or lower GM level instead of top 10 elite level).  In other words, you may be able to outplay 1500's in it but at 1250 live standard you can really improve big time elsewhere to bring your other skills up to par with your endgame knowledge.  

i know kotov i use it as toilet paper i hardly belive gm use his thinking system and when i say grat endgame knowledge i downt mean basic pawn endindgs

Maybe study something about basic positional ideas. "Simple Chess" by Michael Stean packs a lot of information into a small book.
