Why do we take long times to decide which books to read?


First of all, we don't know what our preferences are,


Are you reading for entertainment/ knowledge or Profit?
Find an interest in what you desire to read and have a goal of what are the benefits of your reading,


Choose what is your interest in entertaining yourself,
What kind of knowledge do you want to gain, 
which field you are choosing to profit yourself,


Entertainments have different fields think of which entertainment field you are interested in?
Knowledge about what?
Religious/philosophical/General/sports/films/stories/stories of which type/Literature/Culture/Life/Fitness knowledge ?


Profiting yourself is a part of knowledge, Gain knowledge until you don't feel you are ready to achieve the profit of it.


But the base of all this is Experience in reading different books Until you find your interests.

This book will surely help you to choose what you are choices are
