Self-sufficiency is the development of a person's ability to manage on his own, without fear of loneliness and not needing outside support for good functioning. Imagining a completely self-sufficient person is difficult; therefore, they identify types of self-sufficiency depending on the sphere (social, financial, household). The definition of self-sufficiency can characterize the two poles of manifestation of this quality - on the one hand, a positive influence, when a person is able to do without the others, without suffering (being able to find a job on a free evening, the ability to feed himself, and also contain life), on the other hand - excessive manifestations of self-sufficiency, when the rest of the world moves away, and the person becomes isolated in a recluse shelter.
Self-sufficiency is not only the ability to survive, but also independence in decision-making, life choices, regardless of support or censure by other people. Self-sufficiency does not fit with the concept of dependence, whether it is chemical or emotional dependence on a person. The question of whether this property of the person is positive, cannot have a definite answer, but in society there is a desire to develop self-sufficiency. People are looking for ways to develop self-sufficiency through training, articles, personal coaches and changing life strategies, but few are looking for a way to reduce their self-sufficiency. When she is in that degree of development that is excessive and inadequate in its realization, people usually come with problems of loneliness, inability to build relationships, psychosomatics, or disorders of the affective sphere.
