In 2010, Google estimated that there were over 129 million books published. Even if one is a prolific reader, with the ability to read and remember 20000 books, that is a small percentage of the total. Thus, what you read, and whether it is one of the greatest books ever written, is not material. Because, you can't achieve any goal other than a modest one.
