Reading habits of all kinds are good. It doesn’t matter if you read fiction or intellectual books. However, the kind of books each person reads depends on their grasping power and interests. And reading 500 to 600 pages a day might be possible for some but some might find it difficult to grasp all that they read and will end up getting more muddled each day. So, one can’t have a pre decided number of pages which they can read each day.
