At present, a satisfying, secure job which corresponds to our education is for some of us a normal, logical consequence of our choices made at school, while for others it is an unattainable luxury. What inspired me to explore this topic was my observation of various professional circles and different levels of satisfaction with everyday professional duties, noticeable to a casual observer. I assumed that people working in their field will achieve a high level of the sense of the meaning of life and experience lower depression levels than people performing random jobs, including casual ones. The issue examined was whether, and to what extent, the choice of work influences one's sense of the meaning of life and depression level. It turned out that people working in their field feel greater job satisfaction than those working in other fields or performing casual work. Their job, which meets their interests, is connected with important elements of their life and with their interests in a given field, sometimes having developed from their childhood. The practical conclusions arising from my research may be particularly significant for psychological prevention, upbringing, and education, fields seemingly distant from problems of the adult professional life.
