The work of a manager places enormous challenges on the expertise as well the personage in the great everyday stress of the position. Over the last few years the overall turbulence of the market, work in so called matrix structures, the necessity of frequent change and great speed needed in performance and managerial decisions have increased this pressure. Working in multinational companies brings with it additional particulars such as multicultural environments, communications in multiple languages, cooperation (direct and over distances) with people around the world; at the same time balancing new acquisitions and the fragmenting of individual organizational cultures. How does one unite and integrate all these factors affecting an individual in the managerial role? How does one maintain performance levels, efficiency and one's well-being? The writer captures the particulars of the concept of well-being originating in the ideas of Corey L. M. Keyes and Martin Seligman - the idea of "flourish." She defines the fundamental idea of this idea which, on one hand, diagnostically corresponds to the level of personal prosperity and optimal success and, on the other, may serve as potential criteria for building feeling of living, a subjective extension of each individual.
