The article presents the analysis and results of the study of the peculiarities of the relationship between self-relationship and motivation of achievement in students. The tendency to strive for success is understood as the force that causes an individual to act, which he expects to lead to success. This trend manifests itself in the direction, intensity and persistence of activity. Obviously, there is a mutual relationship between motivation and personality properties: personality properties affect motivation features, and motivation features, once entrenched, become personality properties. Motivated for success, as opposed to motivated for failure, reduce success rather to ability (talent) and great effort (effort). Failure, on the other hand, is attributed to success motivated by insufficient effort, and failure motivated by lack of ability. But the success or failure of an activity depends on ideas about its capabilities no less than on these abilities themselves. Success and failure have a regulatory and formative effect on the self-relationship of the individual, motivation, but also self-relationship of the individual affects the process of human activity. In essence, motivation is an intermediate link between the self-relationship of a person and its behavior. From a practice point of view, this study is interesting as a material for conducting both individual psychological consultations and for compiling programs for psychological adaptation and motivation of students.
