Between 16th and 20th of September 2019, European Academy’s experts have delivered a course on leadership in Athens, Greece. The purpose was to strengthen the technical support efforts in the area of project management and leadership skills to the Independent Authority of Public Revenue in Greece. The course included topics such as Organizational Change, the 5 Levels of Leadership and Neuro-Leadership. During the five days training, participants engaged in discussions of concepts such as the Johari Window and Mihaly Csikszentmihalyi’s concept of Flow. Particular attention was paid to the application of different leadership styles in different situations, since in this way, the future leader can make the change from within the respective areas of responsibilities. The course was attended by many IAPR directors and was very interesting. There was great interaction between us and the participants and we have enjoyed our conversations with them. Overall, it was an amazing experience in all aspects.
