Piracy did the same thing for me. If would read more than 50 pages in a book i would buy a copy, if not i would delete and move on. I think i fully read 21 in 2023, and ditched probably about as many before 50 pages. I absolutely bought and read more books than in 2022, not even close.
I may be wrong, but Kindle samples are often much shorter than 50 pages in my experience. Usually too short for me to make a choice as to whether I want to read the book or not.
