Some caveats:
1) I don’t read that much. Not counting any books related directly to my work, I read between 30 and 35 books last year. That’s a fine number, but nowhere near the book-diet of some people I know. Maybe specifically because of this I might be a better example for some people, as my numbers are achievable.
2) This should not be competitive. Read as many books as you are comfortable with. Don’t read when it stops being fun or interesting or you have better things to do. Also, if you are competitive about this, that will change your habits in a negative way, because you will choose books based on what you can read fast rather than what would be interesting and you will start to read fast rather than digesting what you are reading.
3) I read a lot of non-fiction. I like to read things that will inspire my thinking in some way. This does come with some benefits regarding pacing your reading.
