The title of the post is my subjective opinion and you may not agree with me. But I do believe that there is something good in every book, not because of the famous “finding good in everything” kind of belief but only because there is a subconscious element to writing. There is something bigger than you which guides you when you write. Of course, not every writer taps into this but no matter how ‘commercial’ a writer is, writing IS a solitary exercise. But then, solitude is not just physical, right? You can live in a secluded hut but your mind can still be conditioned. But I do believe that the more you write, the greater the possibility of you getting out of your conditioned mind.
The other reason why I don’t want to close my mind to any book is probably mystical. We usually have fixed ideas about the sources that can give us happiness, wisdom or solutions to our problems. But sometimes, answers or joy come from the most unexpected places. A book may be bad, but sometimes it can turn out to be the perfect book at a particular time of your life.
