Have you ever regretted reading a book- which one and why?

Have you ever regretted reading a book — which one and why?

Have you ever regretted reading a book- Which one and why? I do not regret reading any book.  However, I detested mathematics growing up in Dayton, Ohio.   I know that I am an average student who has an above average intellect, but math has always been one of my weakest subjects in school.  I might as well say that reading a math book has always been very difficult for me.  The Holy Bible is a book that has never been difficult for me because God and Jesus Christ are literally talking to me each time I read it.  God and Jesus Christ will never leave me nor forsake me. Thank you for allowing me to be very honest today.  I really do not know exactly where this question came from, but I do understand that math has always been a very difficult subject in school for me.
