Throughout the last year, I have worked part-time as a working student and also studied at the university. I was not the first and not the last one who has combined that during their studies, but the problem for me was, that at the end of the day I have felt absolutely exhausted mentally and physically. That caused problems with my health and motivation to continue working on my goals or anything. (yeah, “goals,” I wish I had something more specific at that time).
