Read for a purpose, and must set a time limit. Dont read for 3 consecutive 3 hours but three 1-hour section. Be mindful of where the "weight" of the book is. Try to know the intellectual context. A book is usually a response to some other author.
Reading is a creative process, not like watching TV. Work your mind as you read. Question, rehearse, discuss as you read. Use different modes, this will develop your mind fully.
