For most books, I read the reviews first to get an overall impression. But before I really buy and read the book, I skim the chapters to see if the book piques my interest.

Since finishing university, when we had to read all kinds of boring books, I only read books that seem interesting - because I know the author, because of the topic, because a friend recommended it to me... or because I saw it in the bookshop, read the start of it and found it interesting.

I choose a book then asked people who read it what they think about it if they said it bad I will choose other one

Hello :) I normally skim through the book covers first. It's normally the title that urges me to pick up a book, whether I think it's unique, interesting, strange, funny, or odd. I'll see the interesting title, sometimes the cover (but that's not always the case), and read what the book's about. If it seems like something that'd interest me, then I'd get it.
