Consider this: Among our peers, there are always the discriminating types who have adopted a few good books after reading many bad ones. When they say that a text is worthwhile, it deserves reading and careful study.
The person who starts building a working library for their professional use cannot do better than to consult those who are scholars as well as leaders, and ask them to name a few of the more impressive texts.
The well-read person need not have more than a dozen books in their home, provided that they all possess potency and one continues to pore over them and to ponder the weight of what is said. On the other hand, the ignorant person is frequently marked by their bookshelf stocked with titles, not one of which suggests that they have any professional discernment.
Some of these books are really hand grenades described as nonfiction, and will likely cause radical shifts to occur in the foundation of your life. You may also find that listening to any of these as an audiobook could be an enjoyable and convenient option as well.
