It's not about you, it's about the next person. The single best use of a business book is to help someone else. Sharing what you read, handing the book to a person who needs it... pushing those around you to get in sync and to take action-that's the main reason it's a book, not a video or a seminar. A book is a souvenir and a container and a motivator and an easily leveraged tool. Hoarding books makes them worth less, not more.
