Life satisfaction influences sustainable personal growth among students by ensuring that they more firmly apply themselves in their education. Universities represent an environment where students may improve their life satisfaction through better academic performance and being engaged in extracurricular sport. This study evaluates life satisfaction (LS) among university students, 18 to 28 years of age to confirm whether academic performance, involvement in sports and physical activity are factors relating to higher levels of LS among university students. The study uses the Brief Multidimensional Life Satisfaction Scale. Over a three-year timeframe, a questionnaire was administered to a sample of 875 students across areas of study in institutions of higher education in Serbia. The data were analyzed using Mann–Whitney and Kruskal–Wallis tests. LS among students is found to be significantly improved under the following conditions: removing the burden to pay for one’s tuition, having a better Grade Point Average (GPA) as well as being involved in sport. Moreover, the optimum level of physical activity to positively affect LS is found to be four to five hours a week.

The paper presents project manager`s competencies that are critical for managing projects successfully in the digital era. In the beginning, there is literature review in the field of project manager`s competencies and then is presented research conducted on 52 project managers from the most renowned companies in Serbia. The research consists of two parts: the assessment of the competencies importance and the project managers self-assessment. The results showed that conceptual competencies (seeing the overall picture of the project and its connection with the environment, coordination of all elements of the project and having a vision) and relationships with people, are the most critical competencies that project managers should have. Technical skills are still significant but to a lesser extent. Regarding the possession of specific competencies, respondents have conceptual, political and human competencies. Thus, the digital age causes shifting from technical to soft skills such as analytical skills, decision making and working with people.
