A profession simply put means an activity that you do on a daily basis in order to earn your livelihood and make money to sustain yourself. It can also be stated as a vocation, as an area of expertise that you have taken your time to better yourself at over a period of several years. Some common examples of professions are Doctors, Engineers, pilots, scientists, construction workers, engineers, nurses, salesmen, writers, artists, etc. Being of one certain profession means that it is your domain, it may overlap with other professions but by no means indicates that it can be both. A doctor may not be an engineer unless he has devoted himself to the number of years required in that area of interest and vice versa. However, some people may be polymath and can handle many different professions simultaneously.
