Abstract
In a dynamically changing modern society, the problem of personal success in life is becoming particularly relevant. Socio-economic instability, increasing demands for professional and personal self-realization, as well as increased competition in all spheres of life necessitate the search for factors contributing to achieving sustainable life success. In this regard, the psychological determinants of success are of particular interest, among which the individual stylistic qualities of a personality attract increasing attention of researchers. The concept of life success is multidimensional and is interpreted ambiguously in the scientific literature. In a number of studies, it is considered through the prism of objective indicators professional achievements, social status, income level, academic success. Other works focus on subjective criteria such as life satisfaction, a sense of self-fulfillment, subjective well-being, andmatching life outcomes to personal values and goals. Modern approaches increasingly emphasize the need to integrate objective and subjective parameters of life success, which requires an in-depth analysis of the personal mechanisms that ensure its achievement. One of these mechanisms is the individual stylistic qualities of a personality, which are understood as stable ways of organizing activities, thinking, behavior, and emotional response. This group of characteristics includes cognitive styles, self-regulation styles, communicative and behavioral styles, decision-making features, and coping strategies. Unlike relatively stable personality traits, stylistic qualities have greater contextual sensitivity and functional orientation, which allows them to be considered as important predictors of adaptation and efficiency of life in various fields.
