I have over 45 chess books but I don't understand a single one of them

A silman's endgame book has a section for each rating range

This was my (or rather my father's) chess library when I started to learn chess as a kid:

Winning Chess Tactics Illustrated (Horowitz)

Logical Chess: Move by Move (Chernev)

Fischer v. Spassky (C. H. O'D Alexander)

(Although I like Logical Chess for its applicable themes and game selection, I wouldn't necessarily recommend the other two to a beginner, but this was all I had!)

As a beginner, I felt I made the most tangible progress with Logical Chess, although working tactics definitely helped. I put a lot of work into reading this book. I even went through it all a second time. I could see progress when I didn't have to move the pieces over the board to understand variations. The abundance of resources today probably makes chess study confusing for the beginner. I think it would be a good idea to choose three quality books and stick to them. Chess is a struggle and some new concepts won't be easy to understand right away. If you have 45 books, it is probably easier to get distracted from learning one book well. I didn't have a choice but to focus on three books when I started, but you may need to use some restraint to limit your selection. I think studying one book well is much better than superficially reading ten.  (Note I made the distinction of "studying" - it makes a difference to read actively with a board in front of you and ask your own questions.)

 For what it's worth, you need to study openings more. I researched your skills based on your TT vs blitz vs bullet. Your TT rating shows you have the skills to compete with 2000 rated players (in the mid game), but your bullet rating says you don't have your opening skills down. It takes a lot of work to memorize all the openings 5 to 6 moves out, but that's exactly what Bobby Fischer did, when he was a kid. He read over 4000 books on chess. However, the computer makes it far easier and faster to learn all these. It's boring and time consuming, but necessary. Reminds me of a doctor friend of mine. He never opened a book in medical school (his dad was a doctor), but he recorded every lecture. He is very successful now. My point being, hands on experience, against a computer, teaches you what you need to know, without all the reasoning behind each move. It becomes second nature, allowing you to reach mid game, where all the real action starts. As I mentioned before, your TT rating says you have a good mid game skill level and once you memorize the openings your bullet rating will soar.

"... Overall, I would advise most players to stick to a fairly limited range of openings, and not to worry about learning too much by heart. ..." - FM Steve Giddins (2008)
"... I feel that the main reasons to buy an opening book are to give a good overview of the opening, and to explain general plans and ideas. ..." - GM John Nunn (2006)
"... the average player only needs to know a limited amount about the openings he plays. Providing he understands the main aims of the opening, a few typical plans and a handful of basic variations, that is enough. ..." - FM Steve Giddins (2008)

account created just for that?!

I actually think taking more time in the opening in a bullet game and having fast endgame skills when you reach a winning position will be more beneficial to winning the game with a few second left

Excalibr4 wrote (~17 hours ago): "... once you memorize the openings your bullet rating will soar."

Is there a reason to suppose the main interest is in bullet games?

The great secret to improve is to study good books and solve complex tactics. (Yes, the Captain Obvious strikes again!)

Yes because when we are learning sometimes the learning curve is so steep that we become disillusioned with the pain and simply give up, anything that can help is good and like you say motivation is key.

That's pathetic,maybe donate the books to someone who need them really.may be ebay them?

Excellent idea (videos)

Actually videos have the tendency to spoon feed the viewer whereas when you are presented with a text you must at least make the effort to read and assimilate the material.

I read a lot of chess books and enjoy them and learn a lot from them, especially in terms of positional and strategic understanding. A book can be a goldmine of wisdom and learning for those who read them. So, of course, depending on how ambitious you are as a chess player, you should read any book you can get that is related to your particular needs, weaknesses or interests in chess. I recommend the following approach: Identify your particular needs, weaknesses or interests. Select and start reading a book that covers the information you are looking for. If you easily get bored, only read as long as you feel the book is relevant and focus on getting the information you need.
