The term style of life (German: Lebensstil) was used by psychiatrist Alfred Adler as one of several constructs describing the dynamics of the personality.
Adler was influenced by the writings of Hans Vaihinger, and his concept of fictionalism, mental constructs, or working models of how to interpret the world.
[1] From them he evolved his notion of the teleological goal of an individual's personality, a fictive ideal, which he later elaborated with the means for attaining it into the whole style of life.
[2] The Style of Life reflects the individual's unique, unconscious, and repetitive way of responding to (or avoiding) the main tasks of living: friendship, love, and work.
[7] At its broadest, the life style includes self-concept, the self-ideal (or ego ideal), an ethical stance and a view of the wider world.
