This might sound silly, but you should really reflect on this issue. Do you enjoy what you do? Would you rather be doing something else if you had your way? A lot of people you come in contact with would tell you that they are in their current jobs because of the money, or because that was the job they could get at the time.
Infact, in some cases, people study some courses in the university or higher institution because they are the popular ones, or because their parents wanted them to study such courses.
