"Calling" is typically used about priests, rabbis og physicians. Somebody gets an epiphany (sometimes from God) to do something for other people. "I thought I was going to be a lawyer, but then i had a calling to become a missionary." It's possible to say "I had a calling to become a hedge fund manager," but that's normally intended in an ironic way. "Profession" is normally used about clergy, architecture, law, medicine and engineering. "Psychiatry is my profession." Plumbing and garbage collecting are not normally called "professions". "Career" normally implies an achievement of status, or to distinguish that the activity is done for pay and full-time: "He had a really good career as a journalist" = he became at least moderately famous, got paid well etc. "He's a career politician/ athlete" = he does this full time, not as a part-time job

- "Career" usually implies a longer period of time (years) in the same field of work, with typically some sort of progression included. In military this would of course mean going up ranks. "My career as a teacher began in 2001." - "Profession" is in my opinion your "main job", what you do for living. "He's a doctor by profession." - "Calling" is describing the work you do or wish to do, and implies it's something you enjoy. If you're a plumber and you hate it, you wouldn't say it's your calling. There are some dictionary descriptions as well in addition to those I provided here, but this is how I interpret these words in most cases.

This is how I understand it: "Calling" means that thing that passionate you, that you need from the bottom of your hearth, that is like breathing for you, the thing where you feel fullness and a sense of purpose Example: "Bike overhauling is my calling, I can not stop working on this " "Career" are the things that you have done or you are going to do in an specific profession. For example "My career as a dentist was very short, I worked two years at clinics X before discovering motorcycles" "Profession" I think is more about what area of knowledge or what skill sets do you have for perform your job. For example "After that day, I study mechanics and start repairing motorcycles" I leave here the definitions on a dictionary.
