As a Man Thinketh, by James Allen. Think and Grow Rich, by Napoleon Hill. How to Win Friends and Influence People, by Dale Carnegie. These are all examples of 100-year books, or books that remain popular for 100+ years. The goal of every author in the personal development space should be to pen a 100-year book. Talk about leaving a legacy. Imagine writing a book so unique that it spans multiple generations? It survives beyond your own lifetime. The truth is that most books written in our industry are poor regurgitations of 100 year books. Most are written by thought followers, instead of thought leaders. As my old friend and mentor, Brian Tracy, would say, “this is not for you.” Set a goal to write YOUR magnum opus; YOUR 100 year book. Watch this video for more on this legacy leaving subject.
