Self Help and How To
Though the term self-help can refer to any case whereby an individual or a group betters themselves economically, intellectually or emotionally, the connotations of the phrase have come to apply particularly to psychological or psychotherapeutic nostrums, often purveyed through the popular genre of the "self-help" book. Sometimes writers refer to a "self-help movement", though this movement exists independently from self-help books.
A how-to is an informal, often short, description of how to accomplish some specific task. They are generally meant to help non-experts, and may leave out details that are only important to experts, and may be greatly simplified from an overall discussion of the topic.
