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 was one of the earliest books by L. Ron Hubbard that I read at a time when I was fairly new in the workaday world. From this I was able to really get my feet on the ground regarding work. Particularly useful for me was how to handle difficulties and confusion, how to be efficient and how to create good relations with others.
