One of the primary motives of self improvement is to address issues related to personal problems such as jobs, education, health, etc without any external help. The basic fundamental of self improvement, otherwise called self help, is an effort to bring about changes in ones self with guidance from sources such as self help books or internent and not any professionally qualified person, because that in turn would defy the very definition of self help or self improvement.
An important aspect to keep in mind is to follow the source of guidance with full faith because there is no binding force over here to keep the person from just abandoning the self improvement process when it gets tough.
