Life’s too short to read a book you don’t love. At age 50 or younger give a book 50 pages to see if you like it. Over 50, subtract your age from 100 and that’s the number of pages to read before you bail on a book you’re not enjoying. AndI don’t really believe a librarian is thinking about the way these words could be taken. Aren’t you glad your teachers didn’t have this philosophy in high school and college? Think of how bland and stupid you would be if you never read books that made you sleepy, books that made you angry, or books that made your head ache with bewilderment.
when you turn 100, you get to judge a book by its cover! --Nancy Pearl (Librarian and author of Book Lust)
Let’s consider where this "read only what you like" way of thinking leads—Here is a perspective on life which is determined to live by the darkness of one’s own mind. These are ears which itch to hear only the echo of the emptiness between them. These are hearts which are hardened in their foolishness. These are necks which will bend only to the cruelest of masters: sin and death.
My son, if you accept my words and store up my commands within you, turning your ear to wisdom and applying your heart to understanding, and if you call out for insight and cry aloud for understanding, and if you look for it as for silver and search for it as for hidden treasure, then you will understand the fear of the LORD and find the knowledge of God. For the LORD gives wisdom, and from his mouth come knowledge and understanding. He holds victory in store for the upright, he is a shield to those whose walk is blameless for he guards the course of the just and protects the way of his faithful ones.--Proverbs 2:1–8.
