Career success is something you create. It is not an accident. One of the key skills that is needed is the ability to study new material, often without the assistance of an instructor. I think that the best references on study skills are available at a website that is maintained by the Church of Scientology. In some of the more advanced professions, a person needs to be able to fully update their education every few years. I have a great advantage in my career because of this study technology.
