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 handling other people and exhaustion. Six months later, my wife and I were introduced to Scientology and our lives have gotten progressively more fun and better in every way. Our kids have become highly educated, ethical and productive young people by studying in an L. Ron Hubbard school environment.
