superb-there are a lot of jobs that a person can get that could be described that way.but,as far as professions, I can't think of any that would fall under that description. that's why they're called professions, not jobs. professions imply a certain minimum level of education and a degree. smetimes you'll hear of someone being described as a professional whatever. that only means the person has achieved a high level of proficiency,not that what they do is thought of as a profession. hope this is a little bit clarifying,after all, I'm not a professional.
Theres not a legitimate career that doesnt require references and experience and an education. People hire a professiinal they want to know that he or she knows what they are doing. Even in fast food jobs the manager will at least ask if youve had any experience. I guess you could be a drug pusher. Those guys use children so i dont suppose you need much experience.
