Abstract: The relevance of the work is due to the fact that the analysis of indicators of mental and physical health of a person and their mutual influence is little disclosed in the philosophical literature. There is a problem of studying the achievement of well-being in philosophical terms and the factors influencing it, including the connection of existential fullness (fundamental existential motivations) with various positive aspects of the functioning of the individual that make up well-being: autonomy, competence, personal growth, positive relationships, self-acceptance, life goals.
In this regard, we have undertaken a study related to the study at the theoretical level of the relationship between existential fulfillment and well-being. The purpose of the study: to identify the relationship between the components of life well-being and existential fulfillment.
The degree of existential fullness shows whether there is a lot of meaning in life, whether a person lives in inner harmony, whether his decisions and actions correspond to his essence. Life well-being is a subjective feeling of wholeness of satisfaction with one's being.
  The study revealed significant connections between the components of such personal constructs as life well-being and existential fulfillment. As a result of the theoretical study , the following conclusions were made:
The first fundamental existential motivation concerning the possibility of existence in the world is largely related to self-acceptance and competence. The second fundamental existential motivation concerning the value of life is largely related to self-acceptance and positive relationships. The third fundamental existential motivation concerning self-esteem is largely related to personal growth. The fourth fundamental existential motivation, crowning all the previous ones and concerning meaning, is essentially related to life goals and autonomy.
