Does anyone know any good studies?

I haven't had any education on chess before, I just played how I wanted to. So, does anyone know any good studies? I need to learn....um....pretty much everything....but here are some things I want to focus on:

-Some real openings. I only know King's pawn and Queen's pawn, and I don't even know what to play after that, as someone has told me before, I really need to learn some.
-How to spot tactics

Search LeninPerez. His studies are amazing!

@PrimalPotatoMine i would recommend the book logical chess move by move. Or play good annotated games of GMs. As you are playing the games, try at the same time, write your thoughts before you read the comment and try to guess the next move. Try to analyse as well your own games, take a look, where you missed the tactics, mates, and so on. I hope this can help you.

Edit: For tactics, i would play here, or take the books from the polgars.

But first i would learn, the endgames. And the opening principles. Have fun
