Although I did not know for sure what the books contained what I saw is an incredible piece of literature. The concepts found in the books are one of the best systems for managing your life and dealing with the struggles along the way. I have to admit the value in the lessons taught are well worth the money I have invested. I am applying the time management system alone with great success. It’s not magic but simple techniques to help you along the way. I am an avid fan of self improvement writings. This is one of the crowning gems of the future. I have read from the Law of Success to just about all the Nightingale series. Not one contains the same concentration for direct life applications and workable systems in the Neothink source. A great advantage is in these methods and well worth the time and money spent.
