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 Problems of Work.
This book really helped me with discovering the reason and the solution to fatigue. I also got much greater insight into people and how relationships work. But the key datum was the one about fatigue. I handle it quickly and easily and that has make life much more enjoyable!!
