Self Help: Guidelines Rules Etc

I would like discuss various guidelines for a better life. In that context, I am exploring various ideas and concepts, and I would like to chat. I am not using your services as a search engine, so please do not provide me links to any material. Those links distract me and make me lose my focus. There are many ideas, concepts, methods, techniques, rules, algorithms, laws, tips, and guidelines related to what I should or should not do to make my life better. In each successive prompt I will mention what I consider is the name of one such idea, concept, method, technique, rule, algorithm, guideline, etc. If I have made a mistake in the name, then please tell me the correct name. Tell me which subject area does the name originate from. Further, give me a full description of the term, and also where and how I should use it. Next tell me alternative names for the name that I used. Finally, for each of those alternative names, explain to me how the it works and its subtle differences from what my name suggests. Are you ready?
