From the Sports Science Dream to IT Administrator – My Career Path

After my federal voluntary service, I originally planned to study sports science at the German Sport University Cologne. However, due to increased NC requirements, my high school grades were not sufficient, and alternatives at other universities or a long wait time were not an option for me.

So, I began looking for new opportunities. During my voluntary service, I unexpectedly had a lot of accounting tasks, which sparked my interest in business and commercial activities. A business training program thus became the focus – mainly due to its practical nature and the possibility of entering the professional world directly and earning money. I initially put off studying.
