If you want to find out more about Dianetics and Scientology, the best way to do this is to read an L. Ron Hubbard book on the subject. I personally recommend you read Scientology: The Fundamentals of Thought.
This book really helped me with It helped me with making some very important decisions in my life and helped me take a look at my life and see if what I was doing was what I really wanted to do or was I doing what other people wanted me to do with my life. I realized I was doing what others wanted me to do and actually changed my course of life, due to that book.
