Promotion Day, September 14, when I received my PhD diploma, will forever remain one of the most memorable days of my life. Achieving my dream and holding my diploma in my hands, especially on my birthday and in the beautiful setting of the castle, is truly difficult to put into words. I am deeply grateful to everyone involved in the International Joint Cross-Border PhD Programme in International Economic Relations and Management, as well as to all the professors, with special thanks to my supervisor, for their exceptional guidance and support throughout this academic journey. A special thank you also goes to the Head of Academic and Scientific Commitees of Joint PhDs, prof. Irena Zavrl, whose dedication was invaluable in achieving this milestone.
