Has a book or some books helped you become an efficient reader?

I am struggling to become an efficient reader. If you read books and are an efficient reader, what did you read? If so, how did it help you become an efficient reader? Please tell me what you know or studied in detail so that I can also become an efficient reader. If it’s too much to know or too much detail, my DMs are open to learn. I will also read the book if it’s too much to relay to one person. But I’m open to your pointers as well.

The ideal book would make me an efficient reader in reading textbooks. If you know those books, please relay them to me.
