I came across this quote in A Step of Faith: A Novel (Walk) by Richard Paul Evans:
There are far too many people for us to think about each of them during our short stay on earth - like the thousands of books in a library we haven't time to read in an afternoon. But this is no excuse to cease browsing. For every now and then, we find one book that reaches us deep inside and introduces us to ourselves. And, in someone else's story, we come to understand our own.
