This material is intented to be a synthesis of studies and researches developed especially during doctoral and post-doctoral years. Yet, is it inspired from the daily observations and practices, as well as based on authentic life-experiences of real people. It combines theoretical views with data analysis. Eventually, I propose a measure that I hope to serve to the completion of further researches of scholars and of students. If this material meets the needs of the people interested in the science and in the applicability of psychology, than it worth the time and the energy spend on accomplishing it. I honestly wish you to enjoy the reading.
